- *
- * as_warn() is used when we have an error from which we
- * have a plausible error recovery. eg, masking the top
- * bits of a constant that is longer than will fit in the
- * destination. In this case we will continue to assemble
- * the source, although we may have made a bad assumption,
- * and we will produce an object file and return normal exit
- * status (ie, no error). The new option -X tells us to
- * treat all as_warn() errors as as_bad() errors. That is,
- * no object file will be produced and we will exit with
- * error status. The idea here is that we don't kill an
- * entire make because of an error that we knew how to
- * correct. On the other hand, sometimes you might want to
