Unbreak %warning
Unbreak %warning

Since the error directives, including %warning, are now issued in the
final pass only, it is important that we do *not* pass ERR_PASS1 with
%warning.  Rather than playing even more ugly games in error(),
require ERR_PASS1 to be passed in with warnings elsewhere in the
preprocessor, just like the rest of the system.
