One other thing I've noticed, which I think is unrelated, is that there
is a
glitch in directory listing in emacs under cygwin 1.7: If you try to
list a
directory with control-x d, very often the directory listing makes it
look
like the directory is empty when it isn't. Typing "g" (to ask emacs to
redisplay the directory) usually results in a correct listing.

With no knowledge of cygwin's internals, I'd much sooner guess the
changes to the pipe code...
I should have just reported the symptom instead of trying to guess the
cause: Emacs runs the shell command "ls -al" and thinks there's no output.
Here's a second example. I used emacs's "ediff" function to compare two
buffers, and it reported (incorrectly) that there were no differences. So
it seems that emacs called on the shell to run "diff" but didn't get the
output.
Any chance to create a testcase which reproduces this behaviour without
involving emacs? Emacs is hell of a testcase which I won't even touch
with gloves...
Unfortunately, I have virtually no programming experience. I was hoping
the emacs maintainer might be able to help. Or maybe there are some
programmers out there who are also emacs users and would be willing to
try to debug this. There's a file called callproc.c in the emacs
source, which deals with "synchronous subprocess invocation"; it might
be a place to start, but that's just a guess.
