Since Exim uses mostly string_sprintf(), perhaps it is time for
its own *printf implementation instead of internally using libc.
I usually do that in larger projects, which has the advantage
of being able to use format specifiers for sockaddr, off_t
and time_t.

I don't really seen an option other than using 64 bit off_t from the
beginning, and who knows, perhaps some day that may not be enough, too.
Again we had to implement large file support and programs not using it
will be unable to deal with the new possible file sizes.
I don't know if C requires that there must be an integer type that is
large enough to hold off_t or time_t. AFAIK, both must be numeric types,
but I may be wrong in thinking they may be special builtin types with a
range larger than any other type. I also would not mind, if there were
functions to convert from and to their ASCII representation.
