As a thought---I know it's not C89, but what about changing the default
Lua numeric type to "long double" for those that need 64-bit integers? I
checked my 32-bit system and it reports back "12" for sizeof(long double),
and in the 64-bit system, it reports back '16'. To me, that seems like both
would be large enough to support true 64-bit integers.
