> Is this a practical concern? > That seems like such a strong calling convention change I think you are spot on here. The OP's concern may be due to things like this: > For example, let’s take a C Standard function that uses intmax_t, imaxabs It looks like an unusual departure from typical libc functions like strtol(), strtoll(), etc. which have a primary type right in the name. To the untrained eye, intmax_t may look like some promise of portability, when it is actually no more portable than specifying int or long.
