It would be a silly use of autoconf, since gdb just assumes stdarg.h
is there.  As for its not including tclInt.h, it's true that gdb
itself does not, but some of the gdbtk files include tk, itcl and tix
headers that end up including tclInt.h.  Unfortunately, they include
gdbtk.h only after including such headers, so adding a define in
gdbtk.h would be too late.

I agree we should try to keep gdbtk as separate from gdb as possible,
but I thought this define would be ok, since gdb's configure already
has code to look for tcl/tk.  Anyway, here's an alternate patch that I
dislike a bit on the grounds that it doesn't make sure the problem
won't show up again in the future, and it won't trigger any warnings
should gdb proper ever drop the assumption that stdarg.h is present
(unlikely, but... :-)

Ok to install?  Verified to build with OSF4.0's cc.
