Hmm - with that info, I found a little bit of info on cyg-dev about why the
change was made. The problem essentially being with commands that take other
commands after them:

strace ls -l #oops, getopt makes this strace -l ls

It seems like you trade ease of use in some circumstances with difficulty in
others.

I guess it all depends on which you aspire to be closer to, linux or POSIX.

Personally, I'd prefer it if Cygwin didn't enforce POSIXLY_CORRECT, and
people who wanted it could set it in their environment.

Max.
