[PATCH] sys/wait.h fix

[Jakub Jelinek]

Hi!

If someone does
#include <stdlib.h>
#include <sys/wait.h>
in that order and __USE_XOPEN is not defined, __WAIT_STATUS and the like
won't be defined but will be used in the header, so we get parse errors.
Triggered when compiling gcc.

	* posix/sys/wait.h: Define __WAIT_STATUS and the like
	either if stdlib.h was not included or __USE_XOPEN not
	defined.
