    "glib-2.0 G_CONST_RETURN causing GCC 'warning: const' on F31", where the GCC
    diagnostic
    
    > test.c:2:13: warning: const
    >     2 | G_CONST_RETURN char * f();

    had confused me, and "Deprecated pre-processor symbol, repace with const" is
    probably a better warning message than just "const".
    
    (That recent GCC only prints "Deprecated pre-processor symbol, repace with "
    appears to be a bug in GCC that GLIB_UNAVAILABLE_MACRO already suffers from,
    too.  Recent Clang correctly prints "Deprecated pre-processor symbol, repace
    with const".)
