You're missing the point behind the optionality of those types. A lazy
implementor could do as you say, but will save themselves almost nothing
- the time it takes to insert an appropriate typedef in <stdint.h> is
quite negligible. Those types are optional because there's some
platforms with no hardware support for anything that would meet the
requirements for those types, and for which software emulation would be
too difficult. In general, on any implmentation that fails to provide
one of the optional types, there is no mandatory type that will do the
same thing that you wanted the optional type for.
