Oops -- I hacked the autoconf stuff to add the "autopatch" stuff, and
while I generated the gpc-config.h for djgpp, I didn't adapt the djgpp
Makefiles, like the unix ones.

Generally speaking, this is true. However, for GPC, the Makefile is
generated by the toplevel (GCC) configure, with help from a language
specific configure fragment in the GPC dir. The (new) configure in the GPC
directory does some additional checks and writes only gpc-config.h

I believe currently the Makefile is extracted from Makefile.in with the
help of a sed script in the config/msdos dir. This must be executed from
the toplevel configure.bat. That's how djgpp itself does it, and if GPC
follows this convention, it fits the djgpp scheme best.

The reason it is "hidden" in config/msdos is because it's never run
directly by the end user, but by the configure.bat in the GCC toplevel
directory. It's supposed to be transparent.

I'm probably the person to fix all of this, but it may take a week or so,
because I'm busy hacking the win32 GPC right now.

necessarily a good idea. It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead.  -- RFC1925.
