This particular error is due to a glitch in the ifdefs.  Replace

  #if defined(__MINGW32_VERSION) || defined(_MSC_VER)

with

  #if defined(WIN32) || defined(_MSC_VER)

I took at stab at a mingw32-w64 build recently, and there are link-time 
errors even after everything compiles fine.
Let me know how far you get with this!
