Ideally, all diagnostic functions should be declared in diagnostic.h,
not toplev.h.

I'd prefer not to move diagnostic_for_decl out of diagnostic.c --
it'll die shortly.

A pending patch -- which I'll check in as soon as I'm able to
rebootstrap current CVS, cf my report on gcc-bugs -- will add a more
convenient way to pass context to the diagnostic formatting machinery
(that functionnality is needed by the new C++ front-end tree
formatter, and was requested by Zack).

In the mean time, I would prefer you use pedwarn_c99, setting
lang_printer to an appropriate language specific tree formatter and
use a format specifier as exemplified in cp/. 
Does it make sense for you?
