AFAICS, MS does not offer an official way to retrieve the actual Windows
version via the Win32 API layer. GetVersionEx() is unable to detect
Windows versions which are more recent than the compatibility level
advertised in the application manifest.
Cygwin uses the undocumented RtlGetNtVersionNumbers() from ntdll.dll
because even RtlGetVersion() may not return the correct values. See
function wincapc::init()
