Yeah.  I was just thinking that maybe the appropriate investment of
effort is to make [U]INT64CONST smarter, so that it results in a
properly-suffixed constant and doesn't need a cast.  Then it'd be a
lot easier to make these other macros be #if-safe.

Or we could just recast the test in fe-exec.c to not use SIZE_MAX.
Checking whether "SIZEOF_SIZE_T == 4" would really have the same
effect, though it's uglier.
