I suggest to back up a bit, before we turn a minor header update into
a major libc rewrite ;-) I'd rather not do this just because STLport
says we should.

Can you describe what bad things happen if we don't add prototypes for 
those functions to the header?  Perhaps we could find a simpler solution 
for those adverse effects.
