adaint.h, adaint.c (__gnat_waitpid): Moved to expect.c where it is used.

2005-03-17  Pascal Obry  <obry@adacore.com>

	* adaint.h, adaint.c (__gnat_waitpid): Moved to expect.c where it is
	used.

	* expect.c (__gnat_waitpid): Moved here from adaint.c.
	Reimplement under Win32 using Win32 API.
	(__gnat_kill) [Win32]: Properly close the process handle before leaving
	this routine.
