Log:
        * opts-common.c (prune_options): Make static.  Work with decoded
        options.
        (decode_cmdline_options_to_array): Call prune_options.  Don't
        resize option array here.
        * opts.h (prune_options): Remove prototype.
        * gcc.c (process_command): Take decoded options; don't call
        decode_cmdline_options_to_array here.  Use decoded options for
        argv[0].
        (main): Call decode_cmdline_options_to_array here instead of
        prune_options.  Update call to process_command.
        * config/darwin-driver.c: Include opts.h.
        (darwin_default_min_version): Work with decoded options.  Don't
        handle -b or -V here.
        * config/darwin.h (darwin_default_min_version): Update prototype.
        (GCC_DRIVER_HOST_INITIALIZATION): Update call to
        darwin_default_min_version.
        * config/i386/cygwin.h (mingw_scan): Update prototype.
        (GCC_DRIVER_HOST_INITIALIZATION): Update call to mingw_scan.
        * config/i386/cygwin1.c: Include opts.h.
        (mingw_scan): Work with decoded options.
        * config/i386/t-cygwin (cygwin1.o): Update dependencies.
        * config/t-darwin (darwin-driver.o): Update dependencies.

According to original patch this was never tested directly on darwin...
