We've spent an awful lot of effort over the years in coping with platform-specific vagaries of the *printf family of functions. Let's just forget all that mess and standardize on always using src/port/snprintf.c. This gets rid of a lot of configure logic, and it will allow a saner approach to dealing with %m (though actually changing that is left for a follow-on patch). Preliminary performance testing suggests that as it stands, snprintf.c is faster than the native printf functions for some tasks on some platforms, and slower for other cases. A pending patch will improve that, though cases with floating-point conversions will doubtless remain slower unless we want to put a *lot* of effort into that. Still, we've not observed that *printf is really a performance bottleneck for most workloads, so I doubt this matters much.
