Howdy Mark!

I think that when I looked into this I decided that separate switches are going 
to have to be used for f77 vs. f90.

If so, that will have to wait until 4.2. We are about to release 4.1. If you 
want to grab the snapshot and check out our current nc-config, you can tell me 
if it works for you.

Thanks,

Ed
