I'm not sure what the distinction you are trying to make here is? How does machine architecture play into it? It sounds like int sizes are the same regardless of word sizes of the machine, the choices made just happen to have high performance for common machine architectures. Or is it about endianess? Do big endian machines even exist anymore?
