--- Comment #5 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > This is not a target-specific bug.

If I compile a file with '-fdump-fortran-original -v', I see COLLECT_GCC_OPTIONS='-mmacosx-version-min=10.10.5' '-fdump-fortran-original' '-v' '-shared-libgcc' '-mtune=corei7' '-march=corei7' How do you prevent '-fdump-fortran-original' to appear in COLLECT_GCC_OPTIONS?
