Why should MinGW support POSIX? It is a Windows toolchain. Is it a
problem that MSVC++ does not support POSIX too?

A library is portable when it runs on top of the target APIs, not when
it requires to install emulation layers that force the library user to
migrate his software to that emulation layer.
