Not surprising, since it predates ISO C99. But be assured the 200x
revision of POSIX will take care of it...
Actually, I was short of committing them a while ago, but no consensus
could be reached about the implementation of the fastest minimum-width

Note that types these symbols are intended for have not been
implemented yet. (And there are even more of that kind.)
At this point we already have exact-width types and types capable of
holding object pointers, and I can go ahead and add definitions for
minimum-width types and greatest-width types. However, I'd like a
resolution for int_fastN_t types being come up with.
