I downloaded GNU Prolog.
It would not compile in the August 2000 Cygwin development environment
that
has gcc-2.95.2-2 (a version after the B20 version, with a 4Aug00
cygwin1.dll).
The version was obtain yesterday and it was gprolog-1.2.1.tar.gz,
2048KB.
I am not sure, but the 'make Makefile' compilation may have died
around here in cygwin.h:
This is just a note and no fix would make no difference to me. (I
haven't got
prolog running yet. I wanted it to run an Single Transferable Vote
algorithm
many times under a program doing random walks looking for rule
violations,
