Well, yes, but also the fast ones depending on whether storage or speed
is the issue.

I can't see the point of asking for exactly N bits (with no padding and
two's complement negatives) except when matching some external data
structure.  (And there's also the exception for the N-bit unsigned types
where the wrapping is exactly what the algorithm needs.)

Programmers used to complain that they didn't know whether to use short
or int or long or long long because they need 32 bits but they don't
want to waste space -- use int_least32_t -- or that they don't want to
slow the code down by insisting on 32 bits if a wider type is faster --
use int_fast32_t.  These types arose to answer these complaints.  I am
surprised their use is so controversial.
