[Patch, Fortran] PR 37835 -fno-automatic does not work for derived types with default initalizer

[Dominique d'Humières]

Hi all!

The patch for gcc/fortran/resolve.c is the modernized version of Paul’s patch 
in comment 4.
It causes some regressions due to "Duplicate SAVE » warnings. 
They are silenced by the patch for gcc/fortran/symbol.c unless -pedantic is 
used as documented
in the change for gcc/fortran/invoke.texi.

Is it OK for trunk?

TIA

Dominique
