Apparently it more complicated than that:

[Book15] f90/bug% gcc ya_sincos.c -fdump-fortran-original
cc1: error: unrecognized command line option '-fdump-fortran-original'

but

[Book15] f90/bug% gcc ya_sincos.c -fblah-blah
gcc: error: unrecognized command line option '-fblah-blah'

nothing to do with gfortran FE, and

[Book15] f90/bug% gcc ya_sincos.c -fdefault-integer-8
cc1: warning: command line option '-fdefault-integer-8' is valid for Fortran
but not for C
