I just wanted to mention that, perhaps, the 'silly' option ("C") may
actually be the best one, from the point of view of portability. I can
imagine users trying to install Amber in some older systems, and
getting into trouble because they don't have the latest version of
gfortran (For example, RHEL 4 doens't, as you mention yourself).
Unless, of course, we decide to drop support to all legacy systems at

If we go with option "B", may I suggest a similar check on the
configure_at script as well, to decide whether or not to install gleap
if the gcc version is < 3.4? (I still get bitten by it sometimes :-( )
