2003-07-03 _ <guidod@gmx.de>
	* the last merge with Tek was wrong, SORRY.
	* NVRAM stuff is now included, finally
	* need to fix a few doc things

2003-07-01 _ <guidod@gmx.de>
	* adding a new header-fields.dbk
	* reordering docbook entries in doc-index.dbk
	* changing all parts into xincludes - need to copynpaste the
	   entities like PFE and Tek.
	
2003-06-30 _ <guidod@gmx.de>
	* need two_constant_RT declared through DEF_RUNTIME to make it
	   visible to option-ext.c in some variant modes. The file
	   changed however is def-comp.h
	* fixing a few bugs in uppercasing.dbk
	
2003-06-30 _ <guidod@gmx.de>
	* dnw did try on darwin, need to add <sys/time.h> include
	    alongside of <sys/resource.h> on most bsd systems.
	* adding -no-cpp-precomp to bin/configure.ac example
	
2003-06-30 _ <guidod@exgate.tek.com>
	* merging with latest Tek changes to introduce nvram-style
	    option processing.
	* fixing minor problem for build on solaris
	* add doc/uppercasing.dbk

2003-06-27 _ <guidod@gmx.de>
	* modified configure and pfe/configure.ac to pick up a few
	   of the newer ax macros
	* we do generate pfe/pfe.pc and pfe/pfe-uninstalled.pc now
	   via an ax macro
	* we use the newer ax_set_version_info now which makes for
	   better computations of stuff
	* lib/Makefile.am is a new file, the lib directory shall
	   hold a few examples now to test external module generation.
	* the resp. files have moved from ./Makefile.am to lib/Makefile.am
	* no changes to the source code, awaiting merge with Tek changes
	* ooops, adding sys/resource.h detection and a call in main-stdc.c
	    for setrlimit(RLIMIT_STACK) to guard against infinite recursions.
	* a bug in pfe/Makefile.am - change incorrect @DYNALINK@ ... -lm
	    into -lm @DYNALINK@ for each of the three math modules
	* need to fix in bug def-restore.h (already in Tek tree?)
	* adding installation of pfe.pc
	* move to automake 1.5 always and add dist-bzip2
	* modify pfe.spec, use bzip2 as main package format, and bundle
	     the new pfe.pc along...
	
2003-04-25 _ <guidod@gmx.de>
	* create bin/ subdirectory
	* modify main-sub.* to export C API interface for PFE thread
	   on hold - for internal scripting.
	* create bin/pfe-exec example binary
	* try bin/pfe-exec ".s" or bin/pfe-exec "1" "0" "/"

2003-04-26 _ <guidod@gmx.de>
	* no time lately, the changes from earlier this month have
	  been done in the tek archive for quite a time.
	* update with ac-archive 5.51 macros, esp. subdir build

2003-04-09 _ 
	* added to selftests
	* merged with complex-ext (manual editing was needed here)
	* the queryapp selftest did not work: we need to setup the
   	  PFE.term always and the APPLICATION-mainloop setting should be
	  tested before going into stdio-mainloop (and both are set before
	  the default query-mainloop).

2003-03-23
	* automatically adding -no-cpp-precomp on darwin
	* introduce DLLFLAGS / DYNALINK separation to accomodate with darwin
2003-03-22 _ <guidod@gmx.de>
	* add two new ac-macros
	   PATCH_LIBTOOL_ON_DARWIN_PASS_ALL - fix a libtool-1.4 darwin problem
           PATCH_LIBTOOL_CHANGING_CMDS_IFS - fix a libtool-1.4 continuus prob
	* rename @libpfe_LIBADD@ into @DYNALINK@ and make the ldso
	   dependencies of structs.la and complex.la only available
	   if it is does work on this platform - or even required through
	   no-undefined like on windows. Create a "--enable-option" for it?

2003-03-20 _ <guidod@gmx.de>
	* finally - invent a variant that walks the registered wordsets
	   looking for decompiler routines.
	* enhance with emitting the wordset name for a word that was
	   decompiled with a wordset-lookup for RTCOs
	* distribute all RT_SEE codes to their respective P4RUNTIMEs,
	   this includes builds_RT (core-ext), constant_RT (core-ext),
	   value_RT (core-ext), two_constant (double-ext),
	   offset_RT (useful-ext) - only colon_RT and does_RT are left
	   since they decompile the "rest".
	* add knowledge about p4_FXO and p4_SXCO words
	* misc-ext is called "Compatibility" now
	* in CTC, we compile p4code, in ITC, it is p4xt, and there is
	   a typedef that covers the right thing: p4xcode. Let's pick
	   that up in lit_SEE routines in debug-ext and wherever it
	   has been used so far, esp. for aliases of "ip". Note that
	   we have global define P4_REGIP_T to make it easier for us.
	* oops, usage of P4_TO_CODE in p4_decompile_word was utterly
	   wrong - it already is a "p4code*".
	* the "rest" part of p4_decompile must be a p4xcode* as well.
	    This changes the global definition of P4_CODE_RUN and
	    P4_CODE_SEE as well which must return this type.
	* we can now decompile CTC code! well, just some minor quirks
	   are left. E.g. "ENDCASE" did compile an execution-code
	   being "DROP" (p4_drop) which made each "DROP" to be
	   decompiled as "ENDCASE". gee... and same for opening
	   "CASE" which did compile p4_noop.

2003-03-20 _ <guidod@gmx.de>
	* add code in debug-ext to walk the list of registered runtimes.
	* use new macros to register floating-decompiles for FCONSTANT
	    and FVARIABLE in floating-ext
	* remove vocabulary_RT-decompile and use the default visualization.
	    in the process, I've noticed that vocabulary was errornously
	    exported as FXco instead of RTco, oops.
	* default decompiling is now done for MARKER, DEFER, VOCABULARY,
	    VARIABLE, 2VARIABLE, FVARIABLE
	* again, MARKER was exported errornously as FXco instead of RTco
	* adding decompile-routine for ZCONSTANT in complex-ext
	* complex.la not rebuild - rewrite pfe/*.am to pick automake syntax
	    of complex_la_DEPENDENCIES to register renamed-rule. HTH.

2003-03-19 _ <guidod@gmx.de>
	* the XXCO shall be registered in atexit_wl
	* implement P4RUNTIME(p4_runtime) and register RTCOs 
	     to the atexit_wl with that runtime. It allows us 
	     to find all Runtime words later in debug-ext parts.
	* MAJOR BUG seen: the test for redefined-word in header_comma
	     should be on the argument-wordlist, not the CURRENT wordlist.
	     In the normal case, both are the same which is the reason
	     there were no problems so far, but the RTco-loading with the
	     new model did work on the arg-wordlist w/o setting CURRENT.

2003-03-19 _ <guidod@gmx.de>
	* clean NFA2FF and _FFA from sources
	* update obsolete_RT and make some words obsolete now.
	* some other minor changes, e.g. t_putchar in term-lib

2003-03-18 _ <guidod@gmx.de>
	* get rid of term-lib warnings
	* get rid of trigraph warning in debug-ext
	* remove DVaH wordset-code and execution.
	* remove DSeT wordset-code and execution.
	* putchar is defined as int putchar(int) - fix wrapper t_putc
	   in term-lib and get rid of a warning message over there.
	* re-indent term-lib

2003-03-18 _ <guidod@exgate.tek.com>
	* minor fixes to compile without warnings on vxworks
	* solaris compiler problem (alignment error): we need to
	   defeat solaris gcc 2.95 about unrolling memcpy in save_input
	
2003-03-18 _ <guidod@gmx.de>
	* rename pfe-words to engine-ext
	* forgot to remove debug-error-out in file-sub, fixed now.
	* killing some warnings in dict-comp and environ-ext
	* do not call cold_system from boot_system, and replace all
	    references to boot_system with a pair of both functions
	* rename to FX (p4_cold_system) and FX (p4_boot_system)
	* move wordset-loads of extension-modules from cold_system
	    into boot_system. Only WORDS(forth) is kept in COLD.
	* move greeting messages after cold_system and place
	   init_accept_lined also past cold_system
	* fixup complex.la dependencies for renamed magic
	* change SHOW-STATUS from SYNONYM into OBSOLETE
	* change WSIZE from SYNONYM into OBSOLETE
	* save catch-frame on C-stack alone, save-restore RP now,
	     therefore extend p4_Except with ->rpp
	* rename cAtch to catchframe
	* make engine-sub use p4_Except instead of custom jumpbuf,
	    even that not all parts are used for this one.
	* rename p4_run_forth to p4_call_loop and p4_jump into p4_call_stop
	* fixing P4_OFF_T_MAX

2003-03-17 _ <guidod@gmx.de> 
	* forgot to remove debug-error-out in file-sub, fixed now.
	* killing some warnings in dict-comp and environ-ext
	* split off cold_system() from boot_system() and call it
	    explicitly in each corner where boot_system is used
	    now. We prepare for two-stage boot-order here.
	* move wordset-loads of extension-modules from cold_system
	    into boot_system. Only WORDS(forth) is kept in COLD.
	* make p4_cold_system and p4_boot_system FCodes
	* register the interpret_loop as APPLICATION - before
	    processing the boot_system.
	* redefine p4_HERE to be (void**)
	* rename pfe-words.c into engine-ext.c
	* start using p4_Except as jumpbuf in engine-sub
	* put the Except buffer of p4_catch on the C-stack too.
	* rename p4_run_forth into p4_catch_call to flag similarity.
	* rename p4_jump to p4_catch_call_exit
	* SORRY - this does not work, all things deleted, and
	    starting over with the prior version now.

2003-03-17 _ <guidod@gmx.de>
	* start off with an alternative wordset-loader that goes 
	   through calling FX(code) instead of duplicating behavior
	   in dict-comp.c - the new mode can be enabled using a
	   commandline-option "--walk-on". Later in the pfe devel
	   tree it will be the default that needs to be disabled
	   with "--walk-off" to double-check on loader-errors.
	* the alternative wordset-loader pushes the arg on to the
	   SP-stack, puts the name-string as new TIB to be picked
	   up with WORD/FX_HEADER calls. The save_input does use
	   the SP-stack which is just a great idea methings.
	* speedup processing with giving _parseword a quick path
	   to return the static string from the wordset table.
	* interesting: the new mode will reduce the CTC trampoline
	   code to only select RTCO/ITEM pieces. The type-codes
	   for loader-table and RT-header may even be differently
	   in the future, atleast for non-RTCOs.
	* introduce the "___"/"____" as known from my other works
	   which simulates the hadny C99 variable declaration style 
 	   for pre-C99 compilers.
	* the `make check` succeeds! therefore, we set the new mode
	   as the default. Please disable with --walk-off to check
	   whether it actually is the source of a problem when 
	   you experience some in other corners.
	* a user-config USE_NEW_LOADER is added to deselect the
	   default for the new loader-mode. It is 1 by default.
	* let `make clean` work again (removal of doc/src problem)
	* work on local lib-renamed philosophy
	
2003-03-16 _ <guidod@gmx.de>
	* replace _CHECKDLL with a runtime option "--dlerror-on"
	* there seems to be a bug about p4_next_line .vs. p4_read_line!
	* add AC_TYPE_OFF_T to configure.ac - and get _pfe_off_t in
	    consequence to be used in file-ext.c
	* rename fsize into p4_file_size and let it return _pfe_off_t
	* make UL2UDC superflous in file-ext, and put the double-cell
	   directly on the stack. Also make the system clean for
	   long-off_t in these parts: FILE-POSITION, FILE-SIZE
	* the inverse is UDC2UL in RESIZE-FILE REPOSITION-FILE
	* the _is_nullfile alternative did often not do the same
	    stack effect - which is an error of course.
	* mark all locals as registers, possibly killing a localsframe
	    on the C stack for these.
	* rename fn_size to file_size and make it static
	* truncate() needs to be static
	* fn_resize becomes p4_file_resize
	* fn_move becomes p4_file_move
	* fn_copy becomes p4_file_copy
	* configure.ac checking for fseeko / ftello
	* introduce def-config defines for _p4_off_t p4_ftello p4_fseeko
	* replace all fseek/ftell references.. 
	* replace long with p4_off_t where apropriate, including
	     _fextend, file_extend, p4_file_copy, file_size, p4_file_size,
	     truncate, p4_file_resize, p4_resize_file,
	     p4_reposition_file,
	* p4_File and p4_Input contains an "off_t pos" position now.
	    (note: File->size is left as is, it is in blocks)
	* the PFE should now be largefile clean, adding ac-macro
	    ac_sys_largefile_sensitive right in there.
	* glibc fseeko bug found - bug report sent - making a fixup in
	    def-config.h about it.
	* luckily, we do already have a test/file.4th - which did allow
	    to find a bug introduced during that hunt for the glibc bug.
	* introducing P4_OFF_T_MAX to help with p4_file_copy argument.

2003-03-15 _ <guidod@gmx.de>
	* signal-ext does have problems when SIG_DFL is #define'd
	     as (void(*)())0 which isn't a proper function prototype.
	     I can not do more than document the problem in a comment.
	* it seems to have been a problem related to a bad implementation
	    of the new variant of ax_cflags_strict_prototypes. With a
	    new one it just works as it does suppress this option on
	    platforms where signal.h is not done correctly.

2003-03-14 _ <guidod@exgate.tek.com>
	* merge oss changes
	* double-mix /DCELL and DCELLS did never exist
	* header-ext HIDE was never exported
	* shell-os-ext "CD" clashes with "HEX CD" actually - remove it
	* shell-os-ext "$$" was also obsolete for some time, remove it now
	* adjust toplevel Makefile.mk to allow auto: target to
	   reconfigure autotools within tek environment

2003-03-13 _ <guidod@gmx.de>
	* integrate complex-ext by David N. Williams
	* extends PFE/type with two variables
	* need to rename include_HEADERS to include_DATA to ensure
	    that pfe-config.h is _not_ distributed
	* oops - instead rename pfe-config.h and pfe-target.h into
	    _config.h and _target.h - add -I.. along, and modify the
	    sourcefiles to #include pfe/conf.h and pfe/target.h now
	
2003-03-13 _ <guidod@gmx.de>
	* forgot install -> install-all in pfe.spec
	* clean subdir-build macro and pfe.spec to do the right thing
	
2003-03-12 _ <guidod@gmx.de>
	* try to simulate --enable-all with a series of --with-variant
	     calls interpreted by the toplevel configure part
	* now we need Makefile.ax snippet to add the `make rpm` target
	* add `make check` to spec file - hopefully it works like this
	* forgot incl-mix.h
	* move pfe-config.1 into doc
	* move install-man into doc
	* doc/Makefile.am needs some top_srcdir and srcdir references
	* doc/Makefile.am cleaning references to src/Makefile and xm-tool

2003-03-12 _ <guidod@gmx.de>
	* move test-scripts into test/Makefile.am
	* move doc-target to doc/Makefile.am - actually just a removal
	
2003-03-12 _ <guidod@gmx.de>
	* automatic subdir build with a new ac-macro
	* tweak pfe/configure to get rid of acinclude warnings
	* using TARGET_H macro now to create uppercase host/target defs.
	* using modern AC_PREFIX_CONFIG macro as well.

2003-03-11 _ <guidod@gmx.de>
	* start off generation 33

2003-03-11 _ <guidod@gmx.de>
	* forgot a "const" in fmt of to_float (floating-ext/fpnostack-ext)
	* show REGFP when REGLP not available (".STATUS" in misc-ext)

2003-03-10 _ <guidod@gmx.de>
	* USE_STRTOD and USE_SSCANF should be USER-CONFIGs in both
	    floating-ext and fpnostack-ext
	* change the default for these to 1 - should be the better
	    option according to David N. Williams and Krishna Myneni
	* slightly reformat in fpnostack-ext and floating-ext, esp. use
	    #warning with GCC and an error-halt for other compilers.
	* add some headroom for F-stack in floating-ext, can be set
	    with USER-CONFIG FLOATING_HEADROOM

2003-03-07 _ <guidod@gmx.de>
	* through error-checking, add #ifdef _CHECKDLL in dl-ext.c to
	    allow refined testing.
	* badly named new functions, needed s/p4_ftrunc/p4_f_trunc/ etc.

2003-03-07 _ <guidod@gmx.de>
	* after long discussions with Krishna Myneni and David N. Williams
	    the following compromise regarding F>S behavior was found:
	* FTRUNC>S and FROUND>S added to both of floating-mix and fpnostack-ext
	* F>S is a synonym of FTRUNC>S in both floating implementations.
	* FTRUNC is added to both floating implemenations as a complement
	    for the FTRUNC>S function (note: we do have now FROUND and FLOOR 
	    from ANS Forth plus FTRUNC extra but no FCEIL as in math.h)
	* "F-ROT" is added as a synonym of "-FROT"
	* in fpnostack-ext, adding CELL-FALIGNED environment hint that can
	    be checked in implementations on hardware that would SIGBUS
	    when a floating-point is not self-aligned in memory including
	    the stacks.
	* modify test/fpnostack to succeed on all systems that are not
	    cell-faligned - to make it easier to detect real errors.
	* add NEEDS / (ENVIRONMENT?) magic to autoload forth files when
	     NEEDS -<filename> is given. Also strengthen the requirement
	     for now that the filename _must_ contain a dot or slash and
	     also starts off with isalnum character. Remember: NEEDS items
	     must have a length between 4..25 for compatibility reasons,
	     which is a limit not applicable to REQUIRES as such.
	* change p4_required - prepend atexit-wl name with "-" in front and
	     append ".*" if neither of "." or "/" exist in the filename.
	     This is an incompatible change - hopefully no one did use the
	     file:<filename> auto-named functionality so far (e.g. for some
	     reload scripts). I do expect that to be the case and the change
	     to be safe - but who knows for certain :-/

2003-03-05 _ <guidod@gmx.de>
	* dbk/pfe-fth.mk - oops, s/pfe-fth.htm/pfe-fth.html/
	* remove dbk/Makefile - wrong idea
	* adding HPPA to fpnostack-ext section for DOUBLE_ALIGNED
	* floating-mix s/F-ROT/-FROT/
	* add some comments in floating-mix, esp. F>S

2003-03-05 _ <guidod@gmx.de>
	* merge fpnostack-* changes from krishna Myneni
	* add doc/changes generated from ChangeLog

2003-03-05 _ <guidod@gmx.de>
	* need to modify wordset2words.pl for dpans-reading
	* add --nofileref option and use it in doc/Makefile right away.
	* merge floating-* changes from David N. Williams

2003-03-04 _ <guidod@gmx.de>
	* add body.htm and htm->html generation to doc/Makefile just
	     as known from some of my other projects - an easy way to
	     add a common navigation bar to website files.
	* remove SFHOST install-sf target in doc/Makefile - it is
	     superfluous from my own system having a scp-groups script
	* remove PERLXM rule dbk->xml in doc/Makefile - they do not 
	     belong here anymore, same for c->xml, only xml->html
	     is kept for the sake of $(SRCS).tar generation and the
	     various index-lists of old-style doc generation toolchain.
	* rename sfbasics -> htmfiles, and build it from body.htm chain.
	* invent $(DBKS).tar as dbk.tar and filling dbk/*
	* make dbk/pfe-fth.mk index.html target to do `xmlto html`
	      instead of `xmlto html-nochunks` of the htm target
	* pack dbk.tar and unpack with install-docs
	* add *.htm to DISTFINDFILES in toplevel Makefile
	* split sf-index.dbk into body.htm, index.htm, resources.htm,
	        authors.htm and derive license.htm and lgpl-license.htm
	* remove dbk.tar - it is too big (7.7M) and should not be in
	        a source tarball of pfe - instead reference ../dbk/index.html
	        directly and copy the files as they are.
	* instead of "dbk/" subdirectory, use a different scheme
	* rename resources.htm into documentation.htm
	* rework the frontpage
	* oops, need to add dpans.ar and 4thtutor.ar again
	
2003-03-03 _ <guidod@gmx.de>
	* final fixes for aix-cc (thanks Gary!)
	* five new words in floating-mix as wished for.

2003-02-29 _ <guidod@gmx.de>
	* adapt dbk/pfe-fth.mk for local install with some external
	    xml-c-pfe-doc binary. (fix: pfe sources are local now).
	* fix wordsets2words.pl: HOLD -> hold:core: instead of hold::core
	* fix wordsets2words.pl: slightly different behaviour for 
	    some s/...//gsex - returns ALL in my version but NOTHING
	    in the tek version. Use s/...//gsx instead.
	* target "htm" to create pfe-fth.html as `xmlto html-nochunks`
	
2003-02-28 _ <guidod@gmx.de>
        * the AIX 4.1 cc compiler is especially stupid regarding
	  lvalue propagation across type-casts. We introduce a new
	  def-macro P4_VAR that will cast to target type. In the
	  normal case, that is ((_TYPE)(_VAR)) but in the aix-cc
	  case we do use now (*((_TYPE*)&(_VAR))) instead to
	  make it an lvalue of the given type. We throw in the
	  WATCOMC as well, btw...
	* modified files to pick up P4_VAR: 
  	      header-ext.c:198, option-ext.c:141,143
	      forth-usual-ext.c:p4_fetch_plus_plus,p4_store_plus_plus
	      zchar-ext.c:67,69,74,78
	      dstrings-ext:111,371,371,373,
	      dstrings-ext:1222,1225,1227,1299,1300,1301,1302,1304
	      dstrings-ext:1318,1319,1328,1367,1368,1370,1392
	   
	* fix P4COMPILES/FX_COMPILE in chainlist-ext.c
	* disable volatile in signals-ext.c
	* adding include<termio.h> near include<sys/termio.h> to get
	    away with aix term.h to require struct termio but not
	    including the header file itself (similar to solaris).
	
2003-02-28 _ <guidod@gmx.de>
	_ merge with Tektronix CMS..........
	* core-ext.c
	-   many doc updates
	-   COUNT changed slightly in behaviour for values 0..255
	* def-const.h
	-   introduced P4_NEGATIVE to be seperate from P4_TRUE,
	    modified core-ext.c FIND accordingly to use now the
	        P4_NEGATIVE and P4_POSITIVE defines.
	* main-k12.h
	-    typedef for msc_strings 2-dimensional (bugfix).
	* misc-ext.c
	-   doc updates
	-   UNDER+ renamed to (UNDER+) and the term UNDER+ provided
	    with it as an obsolete name - bug report from Anton Ertl
	    that PFE does use an UNDER+ being different from eveyone
	    else. The UNDER+ is comus. We introduce a word +UNDER that

	    time we may make a synonym of UNDER+ and +UNDER.

	-   just doc updates

2002-10-20 _ <guidod@gmx.de>
	_ update FROUND with latest version from Krishna Myneni
	_ this includes an extra configure.ac check for rint() in libm
	_ adding F= and friends to floating-mix as proposed by Krishna
	_ added NEEDS as self-parsing variant of ENVIRONMENT?
	_ modified logging.h prefix-strings to be better suited in a
	  hosted environment with a terminal to show both the forth
	  terminal strings and the stderr fail/warn log messages
	
2002-10-16 _ <guidod@gmx.de>
	_ added integration steps for fpnostack - including user-config
	  defines for the interpret-slots
	_ added user-config for FROUND_FLOOR - changing the default of
	  floating-ext to that of fpnostack-ext as being the correct but
	  slower implementation. The old behaviour is retained as a user-conf
2002-10-12 _ <guidod@gmx.de>
	_ added fpnostack-ext courtesy of Krishna Myneni of kForth fame
2002-10-01 _ <guidod@gmx.de>
	_ added a few gcc 3.2 fixes - still buggy however for many cases
2002-09-10 _ <guidod@gmx.de>
	_ initial support for sparc sbr-threading - incomplete.
	_ partly fixed ia32 sbr-threading - the include-file does not yet go

2002-09-09 _ <guidod@gmx.de>
	_ various small fixes up to here
	_ including a ">name" bug to be fixed
	_ adding another doc page
	_ reworking the toplevel configure/makefile to work smoother than ever
	_ removing some missing's
	_ and cleaning the kitchen ;-)

2002-08-14 _ <guidod@exgate.tek.com>
	_ bug report, win32 compile problem reports, and other valuable
	  comments by Joonas Pihlaja jpihlaja-at-cc-helsinki-fi
	_ removed _image functions
	_ tek-related small changes that should not pop up in sf-versions.

2002-07-17 _ <guidod@exgate.tek.com>
	_ found a little bug about uppercase match
	_ made provisions to live with uppercase and lowercase feature
	  for a long time - added a bunch of new options for them
	_ the wordl_flags have got expanded here
	_ implemented getenv-style for getoptions
	_ some tek-specific additions in term-k12 and host-k12
	_ found out that complete_word was horribly broken, possibly
	  for quite some time, just noticed by testing in the new world
	  of uppercase matching. Added a complete new implementation.

2002-07-16 _ <guidod@gmx.de>
	_ found a bug in main-sub near -I copying routines +1 -> +2
	_ postpone.fs is not newstyle caselessmatch ready - fixed it.
	
2002-07-15 _ <guidod@exgate.tek.com>
	_ prepare uppercase-caselessmatch feature
	_ search_wordlist and find_local will print a warning message
	_ search_incomplete and do_match do not match with oldstyle ones
	_ search_option does already use newstyle, without warning
	_ no configure option has been added to shut off the warning
	  messages in this version to gain the speed that is intended
	  to be there when all p4_strncmpi occurences get deleted

2002-07-10 _ <guidod@exgate.tek.com>
	_ did try with a chain-ext implementation and dumped it. It is
	  however shipped along for reference or future implementation.
	_ implemented chainlist-ext instead and bound two wordlists
	  into the outer interpreter: prompt-wordlist and abort-wordlist
	_ likewise, atexist-wordlist is now officially exported and an
	  extended do-all-words-while has been implement to cover similar
	  executions as for `forget`
	_ in the course, the normal_execute was slightly touched and
	  modified, hopefully no bugs did get it.
	_ added dstrings patch from DNW as show below (ccm version 0.6.28).

2002-06-27 _ <david.n.williams@umich.edu> Version 0.6.26
        _ Fixed bug in ENDCAT so it properly leaves EMPTY$ when
          there is no concatenation in progress.  Also fixed
          ENDCAT specification in dstrings-ext.c, as well as in
          dstrings.html (not in pfe distribution).
2002-06-18 _ <guidod@exgate.tek.com>
	_ move test/* into install-subdirectory share/pfe/test/ so we
	  can have them installed along always without cluttering the
	  space needed. In unixish systems, the test/ directory might
	  also just be a symlink to the pfe test/ directory, so it is
	  always up to date.
	_ rework self-checking of pfe, to make it easier to get along
	  with hundreds of test scripts.
	_ implement chain-ext.c
	_ normal_execute will not go through p4_call/p4_run_forth anymore.
	_ create a macro FX_EXECUTE to make room for optimizations.
2002-06-17 _ <guidod@exgate.tek.com>
	_ add a small fixup for win32 sig handling.
	_ add `make installs` into pfe/Makefile.am, and add an sed-subst
	  for a series of `make install-it` forward-rules to handle some
	  cases easier where make jumps on dirs and filenames of similar
	  name of a phony target.
2002-06-11 _ <guidod@exgate.tek.com>
	_ add _NULLFILE_ROBUST in file-ext.c, just problematic in win32 api
	_ SPY-ENTER and SPY-DEFER for with-spy.c, partial call-threadin support
2002-06-05 _ <guidod@exgate.tek.com>
	_ merge latest changes made for Tek's upd-pfe.exe
	_ test for different variants
2002-06-04 _ <guidod@gmx.de>
	_ fix build issue for i386 -calls and -fast variant
	_ make-check-all still a bit broken
2002-06-04 _ <guidod@exgate.tek.com>
	_ integrate dstrings-ext updates at version 0.6.27
	_ place come_back onto main-sub throw-exit
	_ invert semicolon-hook in core-ext as suggested by DNW
	
2002-05-29 _ <david.n.williams@umich.edu> Version 0.6.25
        _ Fixed bug in SEE-handling for ARGS{ words.
        _ Promoted $GARBAGE? to the regular dstrings word list.
        _ Renamed M" and M` to CAT" and CAT`.  Much more
          descriptive, and Guido's SYNONYM uninhibits the user
          from defining shorter synonyms.
        _ Changed C names and labels to reflect mstring
          (measured string) replacement for pstring (packed
          string) terminology.
        _ Added conditional throw compiles (#if mcount size less
          than cell size) for mcount overflow on cats and Forth
          string copies into the string buffer.  Cleaned up and
          consolidated USER-CONFIG's for mcount size.
        _ Reviewed and updated in-source documentation, updated
          prototypes.
        _ Revised dstrings.html and smodel.html.
        _ Changed the default USER-CONFIG from short-counted
          (nominally 16-bits) to long-counted strings (nominally
          32-bits).
        _ Added $FRAME-DEPTH to debugging section.
        _ Fixed a bug in ENDCAT revealed by testing with
          char-size counts.  Tests with char, short, and long
          all work, as far as they go...

2002-05-13 _ <david.n.williams@umich.edu> Version 0.6.24
        _ Fixed bug in p4_collect_garbage() where a string stack
          scan to update forward links was omitted for dynamic
          strings bound to variables.  Also made the link update
          code more efficient.
        _ Fixed another bug in p4_collect_garbage() by moving
          "target = next;" at top of do-loop from inside to
          outside the loop.
        _ Added $GARBAGE? in the debugging section.  Maybe it
          should be promoted to the regular dstrings word list.
        _ Improved trystrings.fs and renamed as trydstrings.fs.

2002-05-24 _ <guidod@exgate.tek.com>
	_ lots of small changes in between which led to sbr-threading
	  support for PowerPC architecture. Sadly, only a speedup of
	  factor 2 was detected, so we decided to not develop this
	  part further than it is. Note that the portable call-threading
	  does already provide a speedup of 50%, and this should be
	  much more stable. Anyone with a powerpc computer should 
	  probably check for bugs in powerpc-sbr-threading support.
	  Personally, I think that the real problem is the shortness of
	  forth words - the proc-entry code for each native-code
	  function is 16 bytes (4 opcodes), and the exit-code is 8 bytes
	  (2 opcodes), a body-arg is encoded in 8 bytes (2 opcodes).
	  If we could do code-inlining, the proc-overhead would be
	  reduced drastically, but without it, only factor of 2 (or
	  100% execution speedup) is achieved at the expense of
	  having no debugger, no decompiler, no patch facilities.
	_ this will probably the last 32.x version as I'll turn towards
	  other areas of the internal system to add speedups or new
	  features, and it is quite likely that it breaks backward
	  compatibility - the whole sbr-threading and call-threading
	  parts was mostly #ifdefs and change of macros in many places,
	  the ITC-type objectcode should be touched significantly.

2002-04-03 _ <guidod@exgate.tek.com>
	_ wrong sbrx-ac_define in configure.ac
	_ split dict-sub.c into dict-sub.c and dict-comp.c where the 
	  latter includes the loader and compiling words while the first
	  is for dict wordlist build and search and forget.
	_ _missing.c should be linked to libpfe, even that it does not
	  contain anything so far but for a few embedded platforms.
	_ the change from p4_header to p4_header_comma did sometimes
	  forget to place a P4RUNTIME1 - in dict-comp it broke loader vocs.
	  

2002-04-01 _ <guidod@gmx.de>
	_ change saved_input mechanics to allow it to be done in 
	  _included and _evaluate that took RP so far but that's not
	  allowed in sbr-threaded mode. Reduces the test/-series to
	  just two partial-fail and one fatal-knock-out.
	_ sbr-fix +LOOP ... and go back to standard DO behaviour
	_ sbr-fix DOES>
	_ make optimization for sbr-arg-variant - do not need to make
	  a copy of RP to modify it, just save IP value of top-of-RP.
	_ only test/exceptn is left to fail
	_ dont forget saved_input in unnest_input...
	_ DONE !!! --with-sbrx-threadings works best!!
	_ finally: change the names of it:
	  --with-sbr-threading => --with-sbr-call-threading
	  --with-sbrx-threading => --with-sbr-threading
	  PFE_SBR_THREADING -> PFE_SBR_CALL_THREADING
	  PFE_SBRX_THREADING -> PFE_SBR_CALL_ARG_THREADING
	  and adjust the toplevel configure 
2002-03-31 _ <guidod@gmx.de>
	_ sbr-fix for DO / LOOP - the implementation uses the other
	  variant now with RP[0,1] set to SP[0,1] directly - otherwise
	  the implementation was too complex to fit everyting into the
	  i386 registers which did lead to RP overlap in SBR-threading.
	_ loop-test does now succeed.
	_ sbr-fix for fx_skip_string, a.k.a. s" xx" and friends - it
	  does however need a complete ifdef-series and a set of new
	  macros called the NEW_IP macros now.
	_ 2/3 of the test/-checks do work now 
	  missing are: coretest postpone search-order wordsets 
	  (probably due to problems around postpone and friends.)
2002-03-30 _ <guidod@gmx.de>
	_ add --with-sbrx-threading that pushes the body_addr/code_addr
	  via an argument to the runtime/execution routines. Add some new
	  macros for that, compile_xcode_BODY and compile_xcode_DATA are
	  used throughout, and FX_POP_RT_BODY is changed into the two
	  parts of FX_USE_BODY_ADDR + FX_POP_BODY_ADDR.
	_ the _XE routines must be changed later with FX_USE_CODE_ADDR
	_ dont forget to add to all _RT and _XE routines their USE-arg
	  declaration - one can use a macro for that by changing the
	  FCode into FCode_RT and FCode_XE resp.
	_ make all RP-accessing words into compiling words that will
	  compile an execution. This is needed for passing them RP / IP
	  these words include: >R R> R@ >2R 2R> 2R@ I J LEAVE UNLOOP (core-ext)
	  plus K (forth-83-ext) ?LEAVE RP@ (forth-usual-ext)
	  R'@ R'! R"@ R"! R! 2R! DUP>R R>DROP 2R>2DROP (misc-ext)
	_ note: THROW / CATCH are just ifdef'd out
	_ modify mk/Make-H.pl to actually see FCode_XE and FCode_RT
	_ let sbrx IP do at RP[-1] - which actually works
	_ the speedwhile.fs on my 800MHz P3 results in:
	    ITC: 38s   CTC: 35s SBR-CTC: 29s SBR-ARG-CTC: 21s 
	    ITC: 100%  CTC: 92% SBR-CTC: 76% SBR-ARG-CTC: 55%
	_ renaming things a bit for --enable-all and the rpm.spec
	  --with-call-threading => --program-suffix=-call
	  --with-sbr-threading  => --program-suffix=-calls
	  --with-sbrx-threading => --program-suffix=-fast
	_ add some complex i386 register-selection stuff in def-regs.h
2002-03-30 _ <guidod@gmx.de>
	_ add -fast to pfe.spec file representing --with-sbr-threading
	_ FX_COMPILE should use FX_COMPILE_COMMA_XE instead of FX_COMMA on XE
	_ speedwhile.fs says that pfe-fast is 3/4 time of pfe-call
	  note that this is *with* -fframe-pointer
2002-03-30 _ <guidod@gmx.de>
	_ add toplevel configure meta-tions --use-call-threading and
	  --use-sbr-threading that will add a --program-suffix as well.
	_ fix p4_call for 386 - the CALL-NEAR needs an offset target	
2002-03-29 _ <guidod@gmx.de>
	_ added test/postpone.sh
	_ added test/search-order.sh and forth script
	_ modify all .sh files to use a $testcase variable
	_ prepare sbr-threading
	_ fix [COMPILE] - p4_comma -> p4_compile_comma
	_ fix DVaL type in dict-sub (e.g. FORTH-WORDLIST)
	_ ifdef _SBR_THREADING where needed 
	_ --with-sbr-threading variant compiles and boots
2002-03-29 _ <guidod@gmx.de>
	_ fix destroyer-functionality in forget
	_ fix missig pop_rt_body in floating-deinit
	_ `make check` does succeed 100% now --with-call-threading
	_ add FX_RUNTIME1_RT optimization
	_ `make check` does again succeed --without-call-threading
2002-03-29 _ <guidod@gmx.de>
	_ vocabulary-rt did not use POP_RT
	_ rename p4_var_RT to p4_variable_RT to be good for _DEF_RUNTIME1
2002-03-29 _ <guidod@gmx.de>
	_ omit another signal/raise test/*
	_ bug in test/loop-test.sh (wrong temp file)
	_ fix call-threading POSTPONE
	_ fix DOES and option-ext - these did modify the xt with an xcode.
	_ make-check runs now through (well, just LOADM floating fails)
	_ warning-free core-ext
	_ header-sub / header-ext - here some did modify the xt with an xcode
	_ debug-ext - here some did modify the xt with an xcode
	_ invent the optimization FX_GET_RT in place of FX_GET_RUNTIME1
	_ apply to debug-ext, core-ext, option-ext, header-sub
	_ p4_obsoleted_synonym -> p4_obsoleted
	_ p4_create_does -> p4_builds
	_ export def_runtime in def-comp - including some weak variants
	_ add a "-call" variant to pfe.spec to test the variant as system pfe
2002-03-29 _ <guidod@gmx.de>
	_ delete p4_make_header and p4_header - this did need in turn to
	  create a few dummy symbols to attach P4RUNTIMES to. This makes
	  the test/wordsets to run now through. hoorray.
	_ make-check error-count down to 39.
2002-03-28 _ <guidod@gmx.de>
	_ call-threading!!! - it works for many things now, if not all...
2002-03-28 _ <guidod@gmx.de>
	_ add three configure options
	  --with-nosmart ... the code exists for a long time 
	  --with-call-threading ... next step to be implemented
	  --with-sbr-threading ... add some asm snippets on top call-threading
	_ start adding defines in the headers to prepare for call-threading
	_ often change p4xt into new p4xcode - which are the same in ITC
	_ often change *xt into *P4_TO_CODE(xt) - in ITC, the macro is a noop
	_ sometimes change (**ip)() into (*ip)()
	_ in debug-ext, have to disable some sections...
	_ --with-call-threading, compiles, and boots. But that's it.
	_ because the loading-table has been turned into saving the 
	  words-entries directly in the cfa of the words, so how to find
	  and execute them. well, that's the task for the next version.
2002-03-27 _ <guidod@gmx.de>
	_ add SOURCE-NAME to misc-ext in parallel of SOURCE-LINE
	_ change P4RUNTIME into P4RUNTIMES to add a flag for ONLY-CODE
	  to prepare the use of call-threading
2002-03-25 _ <guidod@exgate.tek.com>
	_ add RESET-ORDER-IS exporting PFE.reset_order (search-order-ext)
	  and make an if() around RESET-ORDER within abort_inits and
	  set the default to TRUE in boot_system (engine-sub), so that
	  the default behaviour of PFE is not touched but a user can
	  disable the implicit RESET-ORDER ON ABORT.
	_ let DEFAULT-ORDER save CURRENT too, and let RESET-ORDER do
	  also reset the CURRENT definitions-wordlist.
	_ add --with-static-regs, and modify a few headers and main-sub
	  to use a memory area for the complete ForthVM instead of just
	  a single pointer for single-threaded non-cpur-regs mode. This
	  can speed up the execution for a statically-linked program as
	  the C compiler / Linker can precompute the final address of
	  each ForthVM register and system-variable. Just like the case
	  of the regTH in memory, it allows to compile this PFE also
	  with non-gcc compilers or machines that do not yet have a good
	  register allocation for the ForthVM in hardware registers.
	_ in the course, use main-def.c now, add main-alloc.c, and 
	  modify .STATUS to report the two regTH/regVM modes. From
	  main-sub, four new functions are exported and two extern
	  references for the two global static memory areas called
	  p4_reg (static p4_Thread) and p4_opt (static p4_Session).
	_ note that you probably don't want to use shared-modules with
	  static-regs but it is left up to the packager to decide.
	_ modify the boot-order a bit - after --boot-file, do an
	  implicit DEFAULT-ORDER that includes the FORTH-WORDLIST in
	  DEFINITIONS, then let main-sub load the include_file. Cut
	  out the CURRENT=FORTH_WL in abort_inits, and let it load
	  through RESET-ORDER which might have been modified by the
	  include-script. This fixes some annoyences with includescripts.
	
2002-03-19 _ <guidod@exgate.tek.com>
	_ remove PFE.query_hook, add PFE.lined_accept.intercept
2002-03-15 _ <guidod@gmx.de>
	_ new style had a bug for without-modules, detected on darwin os.
2002-03-14 _ <guidod@gmx.de>
	_ change dl-internal.c loading. Instead of linking the symbol
	  into dl-ext.c, there is now an external call through main-sub.c
	  that sets a new PFE.set->modules pointer in our option area,
	  usually before booting the pfe thread. The problem came up since
	  for win32/darwin we did need to let resolve all symbols, however
	  libpfemodules needs symbols from libpfe, and libpfe needs the
	  p4Words(internal) symbol from libpfemodules. At the same time,
	  this interdependency might violate LGPL rule [2d] when the 
	  libpfemodule contains code not under LGPL, as it is a static
	  interdependency not given through an optional argument nor
	  through a declaration in the headers. After all, the dl-internal.c
	  should get linked to libpfemodule.la, not libpfe.la, and our
	  main-def gets linked with both libpfe.la and libpfemodule.la,
	  and main-def uses a call to declare the address of the table
	  in dl-internal.c to the loader in dl-ext.c : in the course we
	  rename the feature to set->modules standing for set-prelinked-
	  modules-table. Theoretically, they might not be prelinked but
	  dynalinked but that does not make much sense since in that case
	  we could probably dynaload each module on its own through dl-ext.
	_ in the course of changes, I had to note that the zchar-ext was
	  never compiled in the autotool'ed pfe - dear me ;-) - now it's
	  an extra module and put into libpfemodule.la
	_ extend .spec to build -fig,-regs,_forth variants and prepare
	  toplevel-configure to accept --enable-all to configure them
	  all in one rush.
	_ disable the annoying warning in dict-sub - it's about pop_rt_body
2002-03-13 _ <guidod@gmx.de>

2002-03-05 - <guidod@exgate.tek.com>
	_ here's a loooong list of changes in the last year, where this
	  list takes its descriptions from the change-ids at Tektronix.
	  Sometimes I did mark home work, sometimes I did just try an
	  idea at home, and did put it in here the next day from memory,

	  start over with a new baseline cycle
	_ 2296 msc specific
	_ 2291 32.34 cleanups (yes, this is beta stage)
2001-10-xx 
	_ 2023 another point release
	_ 2017 msc specific
	_ 1999 DLSYM implementation
	_ 1994 NTOHL added
	_ 1588 updec changes 
	_ 1430 point release 32.30 for tek internal beta builds
	_ 1407 updec with 32.x generation
	_ 1375 pfe-all version, including realemul (pfe tek offline vers)
	_ 1284 k12xx padding
	_ 1276 goto_state / random / totalmem-optionext changes
	_ 1222 /1227 / 1228 /1229 / 1230 / 1231 / 1233 /1236
	  slowly merge work done @home into the tek tree. The change-ids
	  are for 32.17 up to 32.27 version numbers. The private work did
	  start off at 32.14 in the tek tree code. Have to check later
	  what was done there at home.
	_ 1133 modify lined.c
	_ 1132 tm specific
	_ 1111 create header-ext, assembling related words there, and
	  cleaning up some things
	_ 1046 / 1089 floating.so, added also for tek - the tek tree had 
	  been built without float support since some cpus did not have a
	  fpu anyway. Here we add a floating module for the ones who
	  have it, and install it on the device. The desktop pfe does
	  now always have a floating.so module, but it must always be
	  loaded via " floating-ext" environent? call. Before that it
	  is not available, so the startup pfe binary has a small
	  footprint unless floating-ext is needed for an application.
	_ 1045 small fixes
	_ 1039 k12 gui problem
	_ 1038 meas problem
	_ 1019 to_body non-const - BIG CHANGE!! the additional does-field
	  (called aux in the sources) is killed from the word header in
	  forth. Instead, we put the does-field *after* the cfa-field in
	  the respective words created, where it was *preceding* the cfa
	  until now. Now we don't want to waste memory unnecessarily, and
	  even more, quite some program make the assumption that the PFA
	  is CELL+ from CFA, atleast in the old fig sources. However,
	  these old fig sources do also expect a "<BUILDS" field for the
	  does-words to exist in PFA[0], and therefore add another CELL+
	  to get at the first real value. Here we change the style, the
	  ">BODY" has been an offsetword so far, just adding CELL+ to all
	  values given to it (i.e. like a "->BODY" word). Now the input
	  argument to ">BODY" must be a valid CFA address (or null) since
	  we fetch the value from the CFA, and then check if that CFA
	  value is the runtime of BUILDS or DOES. If yes, we add two
	  cells, if no we add just one cell, and that makes the outer
	  behaviour ANS Forth compatible. I did check with comp.lang.forth
	  that this is a possible mode, and in fact, by theory, a native
	  code colon word does not have any PFA (parameter field) but a
	  very long CFA (code field) where the latter has a size much
	  longer than the CFA call code. In the end, after all this long
	  text, we did achieve another effect: the --with-fig mode and
	  the ans mode of pfe are simply identical for the internal
	  header layout of all words, including variables, colon words
	  and does words. People making assumptions about the internal
	  layout being other than fig or ans asserts will however see 
	  their programs to be broken. That's why, 32.x starts here.
2001-09-xx 
	_ 898 create comus ANEW
	_ 886 msc specific
	_ 793 more --with-k12=offline-msc
	_ 792 full typed comma support, part 1 (for explicit reloc info)
	_ 778 create "LITERAL," as the non-immediate variant of
	  "LITERAL". Follows a discussion on comp.lang.forth about
	  state-smart words and the need to provide a non-statesmart
	  variant for compiling words, in order to clean postpone problems
	  about these.
	_ 773 change internal voc names to bracket-style, including
	  helper words, the bracket-style indicates that they are 
	  immediate vocabularies. Hang the base wordlist into a
	  VALUE FORTH-WORDLIST and make FORTH to use this value.
	_ 765 meas makefiles adaption, tek internal
	_ 678 create CONTEXT? as the count for the context wordlist,
	  this is used to add glue code so that a wordlist is only be
	  put once into the search-order, used to prevent order overflow

	_ 10944 CS-DROP / CS-SWAP implementations
	_ 10941 add R"@ and friends, this proposition was seen and
	  discussed on comp.lang.forth, which I see as a lightweight
	  alternative to LOCALS. 
	_ 10936 in C, a "=" is no sequence point, therefore some code
	  like FX_PUSH(SP[1]) leaves undefined behaviour. Avoid it.
	_ 10928 replace all OUT by p4_OUT, and remove OUT-#define,
	  same for SPAN, add p4_COLS and use it. Some short defines are
	  no good with win32 headers by the way.

2001-05-21 - <guidod@exgate.tek.com>
	_ cleanup some problems about cygwin and mingw targets
	_ create dl-win32.c

2001-05-20 - <guidod@gmx.de>
	_ watcom-c-10 changes. Project-files/Target-files are now
	  included along with a dummy pfe-config.h/pfe-target.h
	  The dos32-pfe32.exe does work great.
	  The dos16-pfe16.exe will fail on startup with out-of-memory
	  and if you use an option to lower memory consumption it
	  will FREEZE WIN-95 !!! Beware of FAT-filesystem corruption !!!
	_ add *.tgt *.wpj to distfindfiles

2001-05-19 - <guidod@gmx.de>
	_ add another way to detect destroyers: check for a destroyer_RT
	  in the XT if the name is immediate, pretty easy and portable
	  to a configuration without an FFA. Actually, I hope to delete
	  the default for FFA to no, and make it again as fig-compatible
	  as possible.
	_ need to replace all references to the DESTROY-bit, mostly 
	  checks are changed to the new word PFE_IS_DESTROYER.
	_ add destroyer_RT near forget_word API in dict-sub.
	_ change DEFER/IS/DOER/MAKE to use PFA[1] always. In non-fig
	  mode, simpel leave PFA[0] blank.... and warn about usage.
	_ add a test/check for defer/make
	_ add fixup for darwin, add fixup for newest crossmingw compiles.
	_ add manpage generation rule for pfe-config ... a debian requirement

2001-05-18 - <guidod@gmx.de>
	_ replace all HAVE_ defines by PFE_HAVE_ defines 
	  (except: HAVE_VERSION_H HAVE_CONFIG_H)
	  hopefully all config.h defs are now changed to pfe-config.h defs.
	_ merge with pfe-30/README
	_ dnw found a superfluous ifdef in dstrings-ext, thanks.
	_ on darwin-1.3, a patch to generated libtool can build
	  a .so-sharedlib of pfe, but the main-exe pfe is bound
	  statically, "otool -L pfe" does not reveal a dependency
	  on libpfe. Actually, the darwin-native sharedlibs are
	  called ".dylib", not ".so". Same for the loadm-functionality
	  of pfe - the configuration did not find any known unix'ish
	  dlopen functions, so the pfe can not dynaload the created
	  external modules anyway. Therefore, ATM, just use a
	  configure --without-modules --disable-shared ... and if
	  you really want to look at the upcoming sharedlib of pfe
	  on darwin, then patch the libtool after configure with
           mv libtool libtool.gen
           sed -e '/archive_cmds=/s:\\\\":\\":g' libtool.gen > libtool	
	
2001-05-17 - <guidod@gmx.de>
	_ fix some issues that come from error-messages
	  from the borland 5.5 compiler.
	_ strncmpi was still used in some places, instead
	  let them all use p4_strncmpi and have it defined
	  in core-sub.h : core-sub.c dict-sub.c dl-ext.c
	  environ-ext.c locals-ext.c option-ext.c
	_ remove check for HAVE_CONFIG_H from _missing.h
	  and let the HAVE_-checks become PFE_HAVE_-checks.
	_ change _missing.c HAVE_ to PFE_HAVE_-checks.
	_ Borland does not use __FUNCTION__, so we have to
	  change logging.h
	_ main-sub.c: locale.h/unistd.h HAVE_ -> PFE_HAVE_
	_ memory-sub.c: P4_ADD does not work in here with bcc.
	_ some void*-calculation must become char*-calculations.
	  p4_to_link paren_dict_limit_
	_ real windows has timeval in winsock.h ... need to 
	  include it in posix-ext.c
	_ real windows does not have unistd.h ... instead it
	  uses io.h for the basic file functions.
	_ fix p4_compiles/fx_compile issues in shell-os-ext
	_ add <io.h> to _missing.h
	_ posix-ext.c needs PFE_HAVE_WINBASE...
	_ need direct.h in shell-os-ext
	_ use pocket_filename in p4_chdir (shell-os-ext)
	_ use PFE_RETSIGTYPE instead of RETSIGTYPE in signals-ext
	_ look for an env-option to suppress install_signals
	_ a few borland-c-55/Makefile fixes
	_ the bcc32 pfe.exe is now there, but it is wrong
	  and throws before one can get to the line-ed.

2001-05-16 - <guidod@exgate.tek.com> 
	_ fixup cygwin32/NT compilation (not yet through)
	_ fixup vxworks/CD bug
	
2001-05-16 - <guidod@gmx.de>
	_ dstrings becomes an external that is compiled and
	  installed by default. Remove --with-dstrings-ext
	_ apply some fixups for dstrings that I did not yet
	  been able to do with the last week or so.
	
2001-05-15 - <guidod@exgate.tek.com>
	_ test round 1: hook --str-buffer-size as generic and
	  let dstrings-ext use it. dstrings-ext becomes fully
	  decoupled, no external module yet. (31.22)
	_ test round 2: hook into k12xx system
	_ make offline pfe.exe a possibility.

2001-05-14 - <guidod@exgate.tek.com>
	_ complete the option-ext system, hook it into the
	  stdc arg-scanning to do generic option-recognition,
	  test it, and make the "map"-facilities to use it.
	_ start off dl-internal.c, extend paren_loadm to see
	  the internal module-wordsets in that table, and
	  hook into environment_Q to try to load a module if
	  an "-ext"-question is seen and not fullfilled by
	  the first run over environ_wl.
	  (move environment_Q implementation to environ-ext.c)

2001-05-12 - <guidod@exgate.tek.com>
	_ start option-ext system.
	_ tests to make it seemingly work
	_ hook it into environment-wl

2001-05-10 - <guidod@exgate.tek.com>
	_ pfe.h changed, for new SWIG version as of .31.x
	_ tests for vxworks environment - need to recompile everything
	  since LOADLIST-feature has been removed.

2001-05-09 - <guidod@gmx.de>
	_ remove all references to p4_tick and replace with their
	  respective calls to p4_tick_nfa or p4_tick_cfa - files:
	  core-ext debug-ext misc-ext module-ext struct-ext
	  toolbelt-ext tools-ext useful-ext your-ext

2001-05-08 - <guidod@gmx.de>
	_ change exception system - a wordset can now declare an entry
	  that sets a pair of exception-number and descriptive string.
	_ the pfe-specific (memstack/dstrings) exception-numbers are
	  rewritten as wordset-entries, the old secondardy-table in
	  excpetion-sub is removed and replaced by a linked-list search.
	_ found a severe bug introduced at dict_allocate-changes (.12-.15)
	  where I forgot declare the memory section of the TIB. The 
	  "make check" did not jump on this bug but the first interactive
	  tests (from above, a "-2049 throw" test) did reveal it. All
	  versions since atleast .15 (.14?) are affected.
	
2001-05-08 - <guidod@gmx.de>
	_ some cleanups in debug-ext and main-sub
	_ clean mis-changes in dstrings-ext
	_ clean some calls in dstrings-ext that should read 'FX(func)'.
	_ add enable_stackthreaded declaration in def-comp to point
	  into the direction that I like to go with the fcode-declarators.
	_ clean up Semant/Semant2 and compile/compile1/compile2 which 
	  did create error-hell with the free-borland compiles on windows.
	  ... using option --with-user-config=_debug_borland_ansi_compilers=1
	  and declaring the semant-structures in def-comp.h
	  ... mostly changing some FX_COMPILE1 to FX_COMPILE in:
	  core-ext double-ext exception-ext engine-sub locals-ext
	  string-ext forth-83-ext forth-usual-ext misc-ext useful-ext
	  your-ext dstrings-ext toolbelt-ext
	_ remove WITHDEF_REGS from $(OPTIM) in Makefile.am
	_ add depcomp to DISTFILES in toplevel-Makefile
	
2001-05-07 - <guidod@gmx.de>
	_ change dict_allocate - use a new helper routine in memory-sub
	  that carves the stacks from dictlimit down. The dict_allocate
	  of the floating-stack is now moved to the floating_init
	  routine. The main-sub dict_allocate routine does not contain
	  a series of function-calls to our helper routine.
	_ can we make dstrings-ext to use p4_dict_allocate ?? and is it
	  better to have an implicit destroyer.
	_ when to move the other dict_allocate parts to their respective
	  wordset' init-routines ??
	
2001-05-06 - <guidod@gmx.de>
	_ change struct p4_Decomp dot skips from an integer to a
	  function pointer of a type that had been introduced in
	  the decomp-split. The old integer-enum is changed to
	  a series of defines of those integers with the correct
	  types so that the old macros still work.
	_ make the default to call the skips member if it is set.
	_ remove a few skips-ids, move the defintions to their
	  files where they are used, and let the corresponding
	  compiles-struct reference the functions directly there:
	  P4_SKIPS_FLOAT -> p4_lit_float_SEE -> floating-ext.c
	  P4_SKIPS_PSTRING -> p4_lit_pstring_SEE -> dstring-ext.c
	  P4_SKIPS_PSTRING_BACK_TICK -> p4_lit_pstring_back_tick -> ..
	_ marg_execution and make_str_frame_execution go from
	  debug-ext to dstrings-ext where they belong. As a real
	  novelty - the execution gets its own CS which gets
	  compiled by its execution-maker that is not actually
	  named in that CS. Let's see if that works...
	_ move engine-sub interpret helpers to their wordsets,
	  these are interpret_float to floating-ext 
	  and interpret_dstrings to dstrings-ext
	  ... and of course, now we need init/deinit routines
	  in these wordsets to register the interpret-routines.
	_ introduce abort-vectorize-field, so engine-sub can get 
	  rid of references to floating-ext and dstrings-ext.
	  Again, the vector-fields must be inited/deinited in
	  their corresponding prim-wordsets.
	_ move the semicolon-execution of dstrings's margs to
	  its wordset. Use a nesting-routine for the semicolon
	  functional-vector that calls the outer semicolon-routine.
	  May be this defines margs even within a DOES> code part.
	_ move xalloc routine for PFE.dstrings from main-sub to
	  the init-routine in dstrings-ext. The dstrings-ext
	  wordset is now largely ready to be compiled as an
	  external module - the only exception is for the option
	  processing and the exception-ids. As mac-os-x support
	  is not fully tested with external modules, I'll keep
	  it as it is.
	
2001-05-05 - <guidod@gmx.de>
	_ found a severe bug in load_llist routine but we wanted to
	  replace the functionality by load_words anyway. The func
	  load_llist is removed, and the module-p4_MODULE helper-func
	  (compiled by P4_MODULE_LIST) does return a P4WORDS-adress
	  instead of a P4_LOADSTRUCT. The definition of a LOADSTRUCT
	  is now obsolete and the def-words macros will be removed RSN.
	
2001-05-04 - <guidod@gmx.de>
	_ p4_dlopen to p4_dlopenext int api change, dlfcn-ext is now
	  renamed to dl-ext completly. next step will be to adapt
	  to the ltdl-api which requires testing a dlfindsym operation
	  on vxworks first.

2001-05-03 - <guidod@gmx.de>
	_ start make generation 31 
	_ dlfcn-sub.c is no more, and so is dlfcn-sub.h, generated until
	  now and used only in dlfcn-ext.c.
	_ debugged the debug-decomp-split style.
	
2001-04-27 - <guidod@gmx.de>
	_ starting off generation 31
	_ rename Changelog to ChangeLog - which is the recommended name.
	_ split dlfcn-sub.c into pieces that are loaded by a -def file.
	  the new fileset is dl-def.c dl-none.c dl-dlfcn.c dl-hpux.c
	  and of course dl-vxworks.c. The dlfcn-ext.c will be aligned
	  in its naming as soon as the dlfcn-sub api is dismissed.
	_ add a main-def.c - currently it just includes main-stdc.c
	  but it offers us the possibility to set the main-type 
	  with a configure-call.
	_ rename configure.in to configure.ac - we will strictly
	  rely on the 2001-year series of autoconf (2.49/2.50+)
	_ add *.ac to the top-level Makefile distexts.
	_ sourceforge download-server for pfe-packages is now
	  http://prdownloads.sourceforge.net/pfe/pfe-%version.tar.gz
	_ the mark>/resolve> change in misc-ext.c
	
--------------------------------------------------------------------------

2000-04-24 - <guidod@gmx.de>
  * dstrings patch by david.n.williams - applied. 
  * tag v96
  
2000-04-23 - <guidod@gmx.de>
  * did a lot of test with the various autoconf automake libtool
    version. Sadly, libtool does not contain the libsdl patches
    to crosscompile to mingw32, so I have to stick to the old
    libtool. Automake 1.4e cvs-version has quite a few bugs, so
    we update to automake 1.4d release. Autoconf cvs prerelease
    is quite fine, however some macros in the aclocal-archive
    had to be updated. Now we have the chance to test with the
    features from newer autoconf/automake atleast. And to use
    enhanced features from next autoconf-generation atleast.
  * --with-modules ... because we can not anymore just try to
    build the modules for crosscompile mingw32 target.
  * add `pocket-pad` where there is `th'pocket`
  * tag v95
  
2000-04-01 - <guidod@gmx.de>
  * well, with the ltmain.sh/ltconfig libsdl, it works now,
    but it does not seem to be able to resolve the module's symbols
    with the pfe.dll - and that's needed for making module dlls.

2000-03-31 - <guidod@gmx.de>
  * lots of tests to build a pfe.dll, and quite a few changes to
    pfe/Makefile.am and pfe/configure.in
  * these are now dependent on $host cygwin/mingw, let's see later
    if that assumption is correct.
  
2000-03-30 - <guidod@gmx.de>
  * use AC_SPEC_PACKAGE_VERSION - changes to pfe/configure.in and pfe.spec
  * new experience with rpm.spec files made me do a major rewrite of pfe.spec
  * change usage of CFLAGS/INCLUDES in pfe/Makefile.am ... an experience
    from Makefile.am files for external-built pfe-modules.
  * start using AC_PROG_CC_WARNINGS
  * clean out optlevel defines
  * factor out gcc -pipe check.
  * delete comments for -Wshadow and -Waggregate-return
  * remove -g addon, and set -Wl,-S at LDFLAGS
  
2000-03-26 - <guidod@gmx.de>
  * update forthprimer.pdf
  * coldboot module section in engine-sub has still not updated
    to load_words for MODULE2 MODULE3
