As a matter of fact, I just started noticing the same "grep" behavior you're
seeing.  I recently upgraded from 1.3.(something) to 1.3.10.  I am often seeing
the grep process complete without matching anything, although when I rerun the
exact command again, it gives me valid output.

I'm also on XEmacs/Cygwin 21.4.6 on win2k.  I haven't noticed the same symptom
with "compile", as I haven't used that in a while (I've been "ant"ing directly
in a shell buffer).
