Thanks!

No, wchar.h simply includes stddef.h.  So there's no problem in that 
case.

It should be decided on a case by case basis.  Please tell the specifics 
of each and every case like that.

IMHO, the prototypes should be added to the headers only *after* the
functions are already available.  Otherwise, we might get conflicts (when
building a package that provides its private versions of the missing
functions), and some people think that the existence of a prototype is an
evidence that the function is provided by the library.
