* Define signed 128 bit int type. * 128-bit signed and unsigned integers
* Define unsigned 128 bit int type. * There currently is only limited support for such types.
* E.g. 128bit literals and snprintf are not supported; but math is.
* Also, because we exclude such types when choosing MAXIMUM_ALIGNOF,
* it must be possible to coerce the compiler to allocate them on no
* more than MAXALIGN boundaries.
