-1: 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

-It's not possible to build the Bitcoin Core code using the win32 version of the Mingw-w64 cross compilers (at least not without
-modifying headers in the Bitcoin Core source code).
