Why would you need two versions of Emacs on the same machine?  If
that's because the CVS version crashes, then (a) report the crashes,
and (b) don't use the CVS version until the crashes are fixed.

One way to do that is to have 2 batch files that set HOME (each one to
a different place) before they run runemacs.exe.

I use the CVS version exclusively, and it runs for weeks without
crashing.  So please report the crashes (to emacs-devel@gnu.org),
because they shouldn't happen.
