Actually, that looks easier than I thought. The current approach to
[U]INT64CONST dates to before we were willing to require the compiler
to have working 64-bit support. I think that now we can just assume
that either an L/UL or LL/ULL suffix will work, as in the attached
draft. (This'd allow dropping configure's HAVE_LL_CONSTANTS probe
entirely, but I didn't do that yet.)
