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. Fixes #66.
