--disable-fortran, then make our best guess at default wrappers
(since F77_FUNC_EQUIV should not be defined in this case, we
will use both double-underscored g77 wrappers and single- or
non-underscored wrappers). This saves us from dealing with
complaints in the cases where the user failed to specify
an F77 compiler or wrapper detection failed for some reason. */
