Hasn't it enabled it also for any other FEs other than C family and Fortran?
Say jit, brig, go, lto?, ...
I think better would be to remove the initialization to -1 and revert the
fortran/options.c change, and instead use in the C family:
if (!global_options_set.x_warn_return_type)
warn_return_type = c_dialect_cxx ();
Unless it for some reason doesn't work for -Wall or -W or similar.
