This is the compressed share file for the garbage collector code which
is intended to be language customizable.  We have used this for our
most extensive experiments with upcalls to the collector from commercial
lisps.  We don't guarantee this will work for you, however.  Its
ultra-experimental, and put here more for browsing than for using.

Look in externalxface.c for the specification of the interface.

To unpack this share file, first uncompress it, then send it to the Bournce shell:

uncompress upcallgc.shar.Z
sh upcallgc.shar

Then try saying 'make dotest1'.  This will require a program called 'ldhide', which can be found in another of these EXTRAS directories.
