Say, we ignored + something that might have been vital.

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.
