Unless there are strong objections, I'd like to just approve this patch
as is and remove the environment variable stuff when a better mechanism
is invented.  This patch is one of a few things that has been languishing
on a branch for a while.  It's been in use in the cygwin binary release
for some time so, while it is ugly, it does work.
