Ok, that's something I can live with.  I don't understand the notion to
keep _WIN32_WINNT at 0x0400 anyway.  The idea of this value is to be set
manually if I *don't* want modern functions, but the default should be
to allow *all* function so it should be at least set to 0x0601 at
present.  I don't see why using w32api should be different from using
recent MS headers.  But, never mind, that's not the point of this
