initstate/setstate

Apparently cygwin has exported initstate and setstate for over ten years
(see winsup/cygwin/ChangeLog-1997), but I can't find a header definition
for it in 1.5.25-11.  POSIX requires these to be declared in <stdlib.h>.

Also, the signatures seem to differ slightly.  winsup/cygwin/random.cc
declares these as:

char *initstate(unsigned long seed, char *arg_state, long n);	
char *setstate(char *state);

but POSIX requires:

char *initstate(unsigned seed, char *state, size_t size);
char *setstate(const char *state);

Could someone please clarify?
