I do not trust myself to write such code in a way that is as efficient
and numerically accurate as the standard library. Especially not for
floating point formats.

Exim already has some private formats for string_vformat(), but for the
actual conversions, it calls the library.
It sounds to me as though I should parameterize the format using a
macro, default it to "%lld" if off_t is long long, and see what happens.
If we hit a system that doesn't know about ll, the chances are that it
is 32-bit, and a suitable setting of the macro will solve the problem.
