These are the only uses of max() that require a constant value from constant parameters. There don't seem to be any similar uses of min(). Replacing the max() by max_const() lets min()/max() be simplified speeding up compilation. max_const() will convert enums to int (or unsigned int) so that the casts added by max_t() are no longer needed.
