From 2cf599b310efffd5dace66cf6e8b9b4df396df50 Mon Sep 17 00:00:00 2001 From: Arseny Kapoulkine Date: Fri, 13 Nov 2015 09:03:25 -0800 Subject: Work around MinGW versions with non-C99 compliant headers Apparently some MinGW distributions have a compiler that's recent enough to support C++11 but limits.h header that incorrectly omits LLONG limits in strict ANSI mode, since it guards the definitions with: #if !defined(__STRICT_ANSI__) && defined(__GNUC__) We can just define these symbols ourselves in this specific case.
