You can do that, in combination with 'AUTOMAKE_OPTIONS = -Wno-override',

... but typically it's cleaner to test in configure.ac whether FFLAGS
was set, and only override it if it wasn't. To find out whether the
user set it or the value was defaulted by AC_PROG_F77, do something like
if test "${FFLAGS+set}" = set; then
user_set_FFLAGS=true
else
user_set_FFLAGS=false
fi
AC_PROG_F77
if $user_set_FFLAGS; then
... (deal with user-set flags)
else
... (deal with defaulted flags)
fi
In the '...' parts, you can either set FFLAGS, AM_FFLAGS, or other
variables of your choice which you then refer to in Makefile.am
settings. Be sure to AC_SUBST those variables (FFLAGS is already
AC_SUBSTed by default, AM_FFLAGS isn't).
Hope that helps.
Cheers,
Ralf
