REVISION -- Note: I included the lister.i file as a zip because it is over 11,000 lines long.
Hello. I am attempting to compile a program named lister.p, that does some genomic work. I can compile some programs in this suite while others always generate an error. I'm not much of a pascal programmer, it's been 15 years since I actually wrote anything in it, but a group of researchers here would like to get this working. Any help will be very much appreciated!
Thanks! Todd
I am compiling on Mac OS X. Here are my specs.

I ran gpc with the following command line:

Reproducable with the latest gpc sources on Mac OS X.

The problem is that GPC lost track of variables. More precisely, the line (in procedure printfeature):
with f^, f^.definition^ do begin
confused GPC. As a workaround you may replace it by:
with f^ do with f^.definition^ do begin
The following patch should fix the problem (note that to re-compile GPC with this patch you need bison-1.875c, eariler versions do not work).

Why not write simply:
WITH f^, definition^ DO BEGIN
or, for completely positive usage, use:
WITH f^ DO WITH definition^ DO BEGIN ... END; ...
