PATCH: libiberty portability

[Mark Mitchell]

This patch makes libiberty a little more portable; these changes were
needed for WindISS, which has slightly non-POSIXy headers.

Bootstrapped and tested on i686-pc-linux-gnu, applied on the mainline.

	* configure.in (AC_TYPE_PID_T): Use it.
	* configure: Regenerated.
	* getruntime.c: Include <sys/types.h>.
	* waitpid.c: Likewise.  Use pid_t, not int, as the type of "pid".
