This is reassuring. The reason I ever looked in the first place was that
no prototype was being generated for ntohl etc on my i386 box. It was
giving me errors regarding __builtin_const_p or whatever, whih on further
investigation occured when __GNUC__ was defined but __STDC__ was not.
I "worked arround" it at the time.
