Yeah, I guess so. I was trying to think of a better way to handle this,
but this seems like the best solution for now.
Ultimately, we'd like to *not* have ``#include "solib.h"'' in *any*
config/*/{tm,nm}-*.h files. Rather, this include statement should either
be placed directly in defs.h, or even better still, in just those files
which require it. But to get to the point where we'll be able to do this,
we'll need to convert the other files which implement solib support over
to using the new mechanisms. The files which need to be converted are
coff-solib.c, irix5-nat.c, pa64solib.c, somsolib.c, and xcoffsolib.c.
(Thanks to Nick Duffek, osfsolib.c has already been converted. It
just needs to be marked as obsolete.)
