-/* Some machines may desire to change what optimizations are performed for
-   various optimization levels.   This macro, if defined, is executed once
-   just after the optimization level is determined and before the remainder
-   of the command options have been parsed.  Values set in this macro are
-   used as the default values for the other command line options.
-

-/* This macro used to store 0 in flag_signed_bitfields.
-   Not only is that misuse of this macro; the whole idea is wrong.
-
-   The GNU C dialect makes bitfields signed by default,
-   regardless of machine type.  Making any machine inconsistent in this
-   regard is bad for portability.
-
-   I chose to make bitfields signed by default because this is consistent
-   with the way ordinary variables are handled: `int' equals `signed int'.
-   If there is a good reason to prefer making bitfields unsigned by default,
-   it cannot have anything to do with the choice of machine.
-   If the reason is good enough, we should change the convention for all machines.
