    Workaround knownfolders.h linker issue when using a recent mingw-w64 snapshot
    
    As of mingw-w64 r5589 the header knownfolders.h was added
    which contains definitions like FOLDERID_Windows
    As these are also part of libuuid.a you'll get linker failures like:
    
    /usr/i686-w64-mingw32/sys-root/mingw/lib/libuuid.a(lib32_libuuid_a-uuid.o):(.rdata+0x0):multiple definition of `FOLDERID_Windows'
    win32/.libs/libgdk-win32.a(gdkdnd-win32.o):gdkdnd-win32.c:(.rdata+0x360):first defined here
    
    Workaround this for now until mingw-w64 upstream has come up
    with a statement whether this is expected behaviour and what
    component should be fixed exactly
