Ah, that...  Your message made it sound as if there's some inherent
problem that prevents autoconfiscation, so I was surprised.

Yes, it should be easy to fix, except for the gdb.ini part: if one
builds the DJGPP port on Windows or cross-compiles on Unix, the
filesystem will allow that name.  So the test needs to be dependent on
the fact that a DJGPP port is being built, no matter what the
underlying OS has to say about .gdbinit.

Note that include/filenames.h has some constants similar to the `;' vs
`:' stuff, so maybe some of GDB sources could use the results of
autoconfiscation instead.
