Thank you for confirming your interest in the project. I have
correspondingly uploaded the entire soure tree as-is to my website
http://members.lycos.co.uk/deckerben on the "Other Projects" page.
I redesigned that page using some Microsoft Formatting Objects. If your
browser jumbles them up, I will get rid of them.

Yes but it turned out to be something low-level and I have avoided grphics
programming up to this point. This was probably half the reason why I
couldn't get any further with xlibemu either. But it is sometimes hard to
tell if NT PCI blockage is the issue or some other software related issue. I
know that both GRX2 and Allegro will run on Windows2000 in VGA mode, which
is why I ask you about it.

There seems to be remnants of a one-time shot at a DJGPP port already
scattered through the code, but it won't go through DJGPP 2.04 without some
more help. Unfortunately, the package lacks a GNU configure script, so
someone would have to route through it and figure out themselves what needs
to be turned on or off.


All the best with ghostscript.
