I mean just for CARDxx and INTxx, i.e. they really only have the number
of bits implied by the type.  XID/Atom/etc, where they're just used as
unsigned long, will have to stay that way.  Shrug.

(And I have no objection to dropping Cray support.)

In what sense is CARD32/INT32 more self-documenting than
uint32_t/int32_t? The only times I've seen people pick up CARD32,
they've gone 'oh, this is a 32-bit value we hand to the video card'.
