2002-01-12  Jim Blandy  <jimb@redhat.com>

	* gdb.base/ending-run.c (main): Avoid messing with setvbuf; just
	call `fflush' after every `printf', so that the output is produced
	at predictable points, regardless of whatever buffering does (or
	doesn't) take place.
	* gdb.base/ending-run.exp: Adjust tests to expect output to appear
	at different points.
