Hi Henry,
You're suffering from an issue that I wanted to solve... I think
that we should be checking in autoconf'ed files (not _pre-configure'd_
files), but others object with my point of view.
You can do it without autoconf, but the problem is that you'll
have to do a lot of hand-editing to make things work properly. Do you
want me to send you the autoconf'ed files?
HTH,
-Garrett
