    gwin32.c: Fix build on MinGW and earlier MSVC
    
    MinGW and pre-2008 Visual Studio does not have NTSTATUS automatically
    defined from including the normal Windows headers, which broke the
    build on these toolsets.  Fix this by including winternl.h, which will
    define NTSTATUS on these toolsets.
    
    This should fix bug 756875 for the glib-2-46 branch.
