Sorry, but this is not a good change, and it is backward-incompatible
(even if .for might not have been used much in practice).

My intention with the recent Autoconf Fortran changes was to go ahead
and let Automake grab those extensions for $(FC) for which an
AC_FC_SRCEXT was issued.  And assume preprocessing for those where
AC_FC_PP_SRCEXT was issued for.  But that is a bigger change.

Cheers, and sorry for my really slow catchup
(also, all of my mail from yesterday got stuck somewhere...)
Ralf
