[Bug fortran/20943] New: Valid option produces warning

[federico dot carminati at cern dot ch]

The following command line produces a warning even if it behaves correctly

[/Users/fca] cat bug.F
        subroutine bug_bug
        end
[/Users/fca] /opt/gcc-4_0/bin/gfortran -c bug.F ; nm bug.o
00000000 T _bug_bug__
[/Users/fca] /opt/gcc-4_0/bin/gfortran -fno-second-underscore -c bug.F ; nm bug.o
cc1: warning: command line option "-fno-second-underscore" is valid for F95 but not for C
00000000 T _bug_bug_
