    glib/tests/refcount.c: Only expect saturation tests to pass on GCC
    
    From grefcount.h, in order to disable warnings when G_DISABLE_CHECKS is
    defined, we need to make use of the GCC-isque-only __extension__ for it
    to work.  This means that in the saturation tests, we can only expect no
    warnings to show if we are building on GCC-isque compilers with
    G_DISABLE_CHECKS defined.
    
    This will fix the refcount-macro test on Visual Studio builds at least.
