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.
