The attached patch removes vestiges of Monterey compiler support from
configure.in.  Apparently Monterey was some ill-conceived 64-bit SCO/IBM
operating system which died in 2000.  Can't see why we need to support it.

You might want to take a look at r16962. It changed a few other things
as well.

Please do put patches into attachments, rather than including them in
the message.

Will do.

Yeah, that's new mail program version suckage.  You would think an Emacs
command called "mail-attach-file" would actually attach the damn file
instead of simply embedding it into the mail message.

Here's the original patch as an attachment.

And a diff for README.  The other changes in r16962 seem to be bug fixes 
which, while exposed by the Monterey port, don't appear to be platform-
dependent.

You can probably commit this :-)

Committed in r74644.
