And as a possible optional extra, one fairly easy way to add type checking woukd be to add an extra dummp printf format string arg, unused by config_found (would cost one useless ptr push at each call, but we can bear that), declare config_fiund __printf_like, and let the compiker do arg verification (correct types, etc) for us. We'd miss correct pointed at type verification but everyone avoids tgat using (void *) anyway.
Provide a few standard format strings for the common use cases, whatever they are, so people just naturally use those (they'd just be things like "%d%d%d%p%u" where the %d%d and %d%p are two key abd data pairs, and the %u is for a null key that terminates things. Seems like it could work to me, but I haven't worken on autoconf cide since the early 80's I think so who knows. kre
