From 73654c2079a234e6e595506faf5c2671d3e96322 Mon Sep 17 00:00:00 2001
From: hendricks266 <hendricks266@1a8010ca-5511-0410-912e-c29ae57300e0>
Date: Wed, 12 Apr 2017 08:30:32 +0000
Subject: [PATCH] compat.h: Add new types, native_t and unative_t, functionally
 equivalent to our current bssize_t and bsize_t, respectively, but generated
 dependably using template metaprogramming when building with C++ >= 11.
