Instead of using "defined(MSC_VER) || defined(__MINGW32__)" to indicate the windows platform, just check for the _WIN32 define instead. Also remove an unused codepath - the removed codepath would only be used under the condition "(defined(MSC_VER) || defined(__MINGW32__)) && !defined(_WIN32)", and I'm not aware of any environment with MSVC or MinGW that doesn't define _WIN32, thus this codepath never was used.
