OK please clarify how I commandeered a thread?  I addressed my email to 
the cygwin list and set my own subject.  I was not replying to any other 
thread.

Also this may not be the best solution, but I use cygwin for 
development.  It may not be the perfect solution but it works well for 
switching development environments.

I posted my comments because there may be someone out there who will say 
"Hey that will work for me too."
