  -<a name="footnote1">1</a>: Starting from Ubuntu Xenial 16.04, both the 32 and 64 bit Mingw-w64 packages install two different
  -compiler options to allow a choice between either posix or win32 threads. The default option is win32 threads which is the more

  -required to support win32 threads conflict with some of the classes in the C++11 standard library, in particular std::mutex.
  -It's not possible to build the Peercoin code using the win32 version of the Mingw-w64 cross compilers (at least not without
  -modifying headers in the Peercoin source code).
