The C programming language is often called "portable assembly" because C compilers exist for nearly every modern system architecture. But I get approx 900 bytes of code when C files containing functions related to case2 are added to the project (but the functions are not called) against 140 bytes when C files related to case 2 above are removed from the project. C++ is ultra portable and has compilers available on more platforms than you can shake a stick at.
