I've managed to rebase your work to the current state of affairs but had to hack a few things to make it compile (I'm using mingw-w64 on windows and doing a 64-bit build). I managed to use clang and ninja to build it (from msys2 repos). A couple of questions:

- Your pthread implementation uses functions requiring Windows Vista or later, is WinXP not a target? Also, I had to manually set _WIN32_WINNT to 0x600 in __config because mingw-w64 defaults to 0x503 or something like that.

- I had to add a few libraries during linking in CMakeLists.txt:

if (MINGW)
  target_link_libraries(cxx mingw32 mingwex msvcr120 msvcrt gcc gcc_eh)
endif()

Is this the correct way to tackle this problem?
