Note that for WSL the Bitcoin Core source path MUST be somewhere in the default mount file system, for
example /usr/src/bitcoin, AND not under /mnt/d/. If this is not the case the dependency autoconf scripts will fail.
This means you cannot use a directory that located directly on the host Windows file system to perform the build.

compiler options to allow a choice between either posix or win32 threads. The default option is win32 threads which is the more
efficient since it will result in binary code that links directly with the Windows kernel32.lib. Unfortunately, the headers
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 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).
