Re: gprolog-1.2.16 doesn't compile under OS X 10.4

Joachim,
I have a version that I have modified to compile with GCC 4.x. My 
modifications involve changing how the obj_chain signature is defined 
(GCC 4.x doesn't allow an identifier to be defined using both extern 
and static in the same file, as I recall). I have not extensively 
tested the change, although it seems to work fine with XGP.

The patch file is:



This includes my Mac OS X GCC 4 diffs *and* my XGP-specific diffs. It 
should work for you without using XGP.
