This should be closed as WONTFIX. If you compile foo.f90
with -fdefault-real-8, then you must compile bar.f90 with
-fdefault-real-8. You're changing the ABI for foo.f90,
but not bar.f90.

It means "Don't use -fdefault-real-8". It is a broken
unfixable option that I tried to remove years ago, but
that was voted down.
If you have code that requires this option, then the
code should be properly ported to REAL(8).
