Re: Users-prolog Digest, Vol 163, Issue 4

Howdy?

In http://babayaga.neotext.ca/GProlog/
there are 

gprolog-1.4.5.amd64.tar.gz

and

gprolog-1.4.5.sparc64.tar.gz

They are a betabeta-test of some fixes Daniel made to run Gprolog 
on the Sparc64 OpenBSD, but they work for amd64 as well.

At one point I compiled this on Linux.  You will need to clean them and run 
configure.  use gmake, too.
