GPC.  :-(

It's broken.  But it *did* work!

I'll try to fix it as soon as possible.

That's in the DJGPP FAQ, section 6.9.

That's in the DJGPP FAQ, chapter 7.  An additional hint:  Stubedit the
linker (\djgpp\bin\ld.exe) to get a transfer buffer with the maximum
size of 64k:

    G:\DJGPP\BIN> stubedit ld.exe
    ...
    Size of real-memory transfer buffer [...]:  64k

According to my experience, time is wasted not in the compilation pass,
but during linking.

Und ob!

Yes.  For most of my friends, this was the final argument to try GPC. :-)

8-)

I would really prefer to work with a direct GRX20 Unit because I expect
it to be more powerful than Borland's "BGI" interface.  So please go on
with it!  :-)

However I join Sven in asking:  Anybody is using Objects with GPC?

I am thinking about improving object functionality, but if I am the
only one who uses them, it's not worth the effort because GPC's objects
essentially meet my needs like they are right now.
