??? Could you spell out the problems?

There are dozens of GNU projects, all of them using Autoconf (and also
libtool, for that matter), that were ported to DJGPP by running the
configure script with minimal changes (akin the config.sed script used
by GDB).  I'm not aware of any problems that would stop the show for
you, but perhaps I'm missing something.

What do you mean by that?  What ``DOS file support'' in GDB needs to
be autoconfiscated?
