Yes, the prototypes are in machine/profile.h. It is common practise
to have the prototypes include (void) and leave it out for the function
declaration. Anyway, if you stumple over a function without prototyp,
that is a bug and should be noticed. Anyway IIRC in ISO C a function
without arguments might be considered as K&R style and therefore an
implicit (...) is assumed. This does not happen if a ISO prototyp was found.
