Nope. You are spot on, Joel. And, thanks for offering independent
verification of this point.

There are issues involved with using two versions of cygwin1.dll on the
same system and they can manifest no matter how much binary editing you
do or source code modification you do. It is safest to have only the
most recent version on your system.
Cygwin wasn't designed to be distributed as a standalone DLL. While
you can do that, this practice, like the use of MS-DOS paths is not
something that is guaranteed to work 100% correctly.
