Or the compatibility function would need to know which escapes to emulate (or even emulate a super-set of escapes, as long as they don't conflict). If the calling code already has a way to know which escapes to use, then the compatibility code could easily be customized to handle the right ones in the same way.

If the decision is made to not use a compatibility snprintf library, then configure will need a separate test for the limit being off by one, and then a fixing function would need to pass through limit-1.
