Compile failure on 32-bit Mac OS X about pcg-c HOT 2 CLOSED

Same on NixOS: http://hydra.nixos.org/build/25146085/nixlog/1/raw

from pcg-c.

I run into the same issue on a Cray XC30 system

The issue seems related to the test of #if SIZEOF_INT128 on line 48 in pcg_variants.h
as a hack, try taking the test out. and set typedef __uint128_t pcg128_t;

A second issue in extras/pcg_spinlock.h, the #ifndef __has_include test is failing
as a hack take test out and set #define INCLUDE_OKAY(x) 1

The code compiled and was able to build libraries and run the tests
Performing a quick sanity check...
