Compile error in qglobal.cpp under Cygwin

Hi,

Qt/src/corelib/global/qglobal.cpp fails to compile under Cygwin:

QSysInfo::WinVersion QSysInfo::windowsVersion()
{
    // snip
    OSVERSIONINFOW osver;
    osver.dwOSVersionInfoSize = sizeof(osver);
    GetVersionEx(&osver);

This fails because it is passing a wide character variant of the version structure to a normal GetVersionEx(), which can either be wide character or ANSI. Instead it should either use OSVERSIONINFO or GetVersionExW() to avoid mixing. Possibly you could also #define UNICODE, but that seems like a hacky solution.

Also see the documentation here: http://msdn.microsoft.com/en-us/library/ms724451%28VS.85%29.aspx, and the definitions in winbase.h and winnt.h.

Thanks,
