Well, add other options for <warnings> then ;). <warnings>none (disable warnings) <warnings>default (typical warnings) <warnings>high (all warnings that aren't considered "painful") <warnings>all (all warnings) Of course, the names and categories would need consideration when viewed portably. For example, <warnings>all would imply -Wall for gcc, which should also be used for <warnings>high (?), so some users might mistakenly use all when they should use high instead. But I think you could come up with a reasonable way to declare this portably, and believe it would be useful. I'd use <warnings>all from the command line to "lint" my code with VC (even VC6), but would prefer to leave things at the "default" level in the Jamfile to more closely meet user's expectations (too low and when they use my code they get warnings we don't report, too high, and when they use bjam on their own code they may get warnings they don't care to see). -- William E.
