I made the T3E declaration change.
You can either send build options files to this list as attachments or
we can can give you check in access to CVS as long as
(1) you're happy to be careful i.e. do regression tests if you do
futz with something, put up with being on our mitgcm-cvs and
mitgcm-devel mailing list that shows checkins etc....
(2) you won't get offended if/when you get flamed for doing the wrong
thing - even if the right thing wasn't clearly documented anywhere!
