I personally think it would be fine -- C99 is nearly 20 years old now,
surely we can afford to upgrade -- but I think this would have to be run
by the binutils list as well.

Also there's the question of how it would be implemented.  Like, if it
relied on modifying CFLAGS, then that would still interfere how this is
supposed to be a user-controlled variable.
