Of course, #error: has only one implementor :) (Ok, two, but I'm not
counting the second one, so it's only one!)

Default case you could record to a log file and move on.

More interestingly, you could define a table of the error strings, and put
the appropriate handler there. That might not be too bad, for most cases.

The default could be to try proceeding and if it didn't work again, give
up. (That's often what I do :))
