Hello Boost Users, why does Boost use a 32-Bit API for multithreading on a 64 bit system? The Win32 API header on MSYS2 uses 64-Bit Windows API and the Boost implementation (win32_api.hpp) uses 32-Bit which makes my compiler (gcc 6.3.0) complain. Do I have to configure Boost to be 64-Bit? Regards Andrej
