[RFC] warning: initialization discards qualifiers from pointer target type

    warning: initialization discards qualifiers from pointer target  
type

This warning can not be disabled using -Wno-cast-qual
(or any other warning flags). Is it intentional ?
Otherwise I'll prepare patch.
Thanks,

        return "abc";

int main( void )
{
        char *s = a();
        return 0;
}
