Why not? As long as your program is standards-compliant, it should work on any computer with a working C compiler…

- integral sizes aren't standard

- little vs big endian

- signed int layout

- float layout

- includes vary

- bit field implementations vary

- loads of undefined and implementation-defined behavior

The only thing that can change is implementation-defined behavior, and this can be detected and guarded against. Undefined behavior cannot exist in a standards-compliant program.
