    That does work, but there are still things you can't turn off with -f.
    They're half-aliases. toplev.c::parse_options_and_default_flags does
    set -f flags based on the optimization level, but there is still a
    whole lot of gcc code that directly tests the value of optimize and
    optimize_size.
