-/* 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.
-
- LEVEL is the optimization level specified; 2 if -O2 is specified,
- 1 if -O is specified, and 0 if neither is specified. */

-/* 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.
