Sorry.  I didn't read your email as thoroughly as I should have.

Scratch all of the above.  You've stated that you're using an old,
unsupported version of Cygwin.  If you didn't save your original mount
state there is no way to get back to the pristine state.  You can umount
some of the obvious stuff above though, and remount c:/cygwin/bin
without the -X.

And, FYI, Cygwin 1.5 is in an "as-is" state.  We don't really support it
here anymore.
