Guilty as charged.  That was it.  Thank you.
I did one better and uninstalled MS SFU, which is about what it deserves.
Now it works as preditcted.

Thank you for the help, and for the clue-by-4 on the diagnostic tool that 
uncovered the problem.

Hmm, interesting.  I tried both ways, and they both worked identically for
me, so I posted the one that used less space...

Ah, I think this may be your problem.  Are you *sure* you're using the
Cygwin grep?  In general, mixing MS SFU and Cygwin in the PATH is not a
good idea.

Try explicitly using /bin/grep, i.e.,

$ /bin/grep o regexps
oo
$ echo $?
0
$ /bin/grep Z regexps
$ echo $?
1

I see a functional difference in your example and mine.  
You ran grep then echo separated by a ;, 
while I ran it on two separate lines.  
These should do the same thing (as it does on my other target, AIX), 
but it doesn't appear to.  

When I run your example in my Cygwin pdksh shell, 
I get the same results as you.  It looks like I can use 
that format as a workaround for the problem, but I sure
would like to understand why it doesn't work as expected in my 
example, when both examples produce the same results in AIX's ksh,
so I can predict these kinds of problems in the future better.

Thanks for your help.

Can't reproduce this here, sorry:

$ pdksh
$ cygcheck -f /bin/pdksh
pdksh-5.2.14-3
$ grep o regexps ; echo $?
oo
0
$ grep Z regexps ; echo $?
1

Well, this seems to be a problem with your Cygwin installation, but that
aside, using bourne-shell syntax should work for both bash and ksh.

I *did* STFW first.  The closest thread I could find is "negative error status:
gcc vs. cl", which invloves both negative exit values and Windows commands,
neither of which are relevant to my problem.  I'm trying to use Cygwin binaries
inside Cygwin's pdksh shell, and expecting 0 or 1.

If you can recall anything else about the thread you mentioned, I would
appreciate it.  For what it's worth, the search page will not let me search on
"$?".  I tried searching for "ksh exit"

Thanks for your help.

  This one already came up very recently.  Search the list archives.
