This is because Cygwin uses the Windows registry to store
configuration, and there's only one copy per user. If there were one
copy per process, it would not be a problem. Cygwin should dump the
registry and use environment variables. This is supposed to be Unix,
isn't it?

Sometimes you can get by with managing PATH carefully, but more often
you need to keep editing the registry to maintain two versions of
Cygwin.

It does work under Emacs; I've used it to compile Maxima (another
project opposed to Cygwin).
