OTOH,
just including "config.h" is a real common thing to do across all packages.
I can imagine this coming up again and again.

IWBN if hacking on gdb didn't require special cases to standard
programming paradigms wherever possible.
Can we arrange for config.h to include gnulib's config.h?
Or, another thought would be to have configure generate gdb-config.h
(or some such) and then have src/gdb/config.h include both (and similarly
for gdbserver - haven't looked at the details though).
