	* expect.c (__gnat_expect_portable_execvp): New implementation. The
	previous implementation was using the C runtime spawnve routine but
	the corresponding wait was using directly the Win32 API. This was
	causing some times a lock when waiting for an event using
	WaitForSingleObject in __gnat_waitpid. This new implementation uses
	the Win32 CreateProcess routine. Avoiding mixing C runtime and Win32
	API fixes this problem.
