    To make a c++ program portable, don't use non-portable libraries
    or assumptions about a specific architecture.
    There are libraries that are native to DOS only others native
    to UNIX only - don't use them. 
    Don't use assembly language, direct memory access, or unfortunately
    assumptions about the size of primitive data types. Even thought
    a char is a byte on every system I've used, and int may be 2 or
    4 bytes, and a long int may be 4 or 8 bytes.
