I like designated init, "//" comments, varargs macros, "for (int i = ...",
_Bool, and even declaring variables at point of use (but I know others
dislike this one).

I see C99 as a convenience upgrade.  None of those things will markedly
improve gdb's quality, they may just make the hacking marginally nicer.
For me of course C99 is the runner-up choice ...

IIRC there was some concern about library issues.
Or maybe that GCC doesn't implement all the IEEE additions?
I don't really remember now.  It's in the list archives.
