 For good C practice, we should have separate signed and unsigned values
 for the ssize_t and size_t ceilings, and avoid signed-to-unsigned
 comparisons.  See comments in bug #2337 for background.

 (We don't want to just make SIZE_T_CEILING unsigned and use it everwhere,
 since comparing a ssize_t to an unsigned SIZE_T_CEILING is just as broken
 as comparing a size_t to a signed SIZE_T_CEILING.)
