Well, GPC actually appends TARGET_EXECUTABLE_SUFFIX which can be set
by the backend target specification. I assume it's not set in the
DJGPP backend, but I don't know why. Historically it was because
there was reason for the COFF file; if that's no more the case, it
could have been set by default, AFAICS. (That would be a matter for
the GCC developers, in particular for the DJGPP backend.)
If you want to hack it yourself, you can probably just insert
#define TARGET_EXECUTABLE_SUFFIX ".exe"
near the start of p/module.c and rebuild GPC (untested).

Unix says, the right tool for the job.
Why use perl when awk will do, or awk when sed will do, or sed when
tr or grep will do (at least that's my principle) ...

Since PENG is slightly OT here, I'll keep my answer short. For more
discussion, please PM (f.heckenbach at fh-soft.de) or the PENG mailing
list (see http://fjf.gnu.de/peng/ under "Contact").
PENG should support GPC compilation, ideally simply by pressing F9.
Options can be set under "Options/Pascal". "Options/Pascal/Show
sample GPC command line" will show what it will actually use. If you
don't get along with this, you can also enter a command under
"Options/Try a tool" (using the current file name as "$EDNAME",
appyling file name functions etc., see the online help), and if it
works for you, you can permanently define it as a tool under
About the printer, do you get: "file 'prn' cannot be opened for
writing"? (And yes, I agree that accessing the printer via a device
file is silly, but that's the way it is/was under Dos.) After
pressing Esc, will it work normally? (If that's all, I could
probabably get rid of this somehow.)
