This should have the effect of checking out a fresh copy, and doing
touch Mmake.params && autoconf && mercury_cv_low_tag_bits=2 \ mercury_cv_bits_per_word=32 \ mercury_cv_unboxed_floats=no \ sh configure --prefix=$INSTALL_DIR && mmake MMAKEFLAGS='EXTRA_MCFLAGS="-O5 --opt-space" -j6' tar
If it passes all the tests, it should put the resulting tar file in /home/mercury/public/test_mercury/test_dirs/mercury-latest-stable and ftp://turiel.cs.mu.oz.au/pub/mercury/beta-releases.
Make sure you test all the programs in the `samples' and `extras' directories.
