If you prototype them, you'll get something self-consistent
which then runs properly on any version.
My guess is that C_PROMOTING_INTEGER_TYPE_P is intending to
implement the integer promotions as defined by 6.3.1.1/2.
If so, we probably ought to be checking for enumerations as
well. Which would make a difference for -fshort-enums.
Thoughts?
