Good catch.
I agree that one should also consider stdlib.h for limited purposes.

That means the most standard headers to use are any of float.h, iso646.h, limits.h, stdarg.h, stdbool.h, stddef.h, and stdint.h, so long Clean C is also achieved.  (I suspect that rules out stdbool.h.)
Adherence to this discipline rules out all means of dynamic memory allocation other than by user-supplied callbacks. Since the PHS() prototype doesn't have any such callbacks in it, this would preclude implementation of any hash algorithm with configurable memory-hardness.
