IMHO for 32-bit architecture upwards I would make "int" to be fixed to
32 bits long for practicality. Then you can have "int8", "int16",
"int32", "int64", "int128", etc.
This is due to the fact that since ANSI C 1989 (ISO C 1990) came out
most C compiler implementations for 32-bit machines for "int" have
been 32 bits for about two decades; and overwhelming number of
applications have been written with that in mind. Although 64-bit
architectures were available at the time, but it was not nearly as
common as 32-bit architectures until recently.
But, finally it's up to you :-)
