Porting your program to a different platform makes it a different program. It doesn't change the completeness of the original. Modifying your program to account for API changes also qualifies as "a different program" - you can have different programs that all do the same thing, for different platforms, for different API versions of the same platform, and have them all be "complete" even if you may need to write a new one at some point because you want to run it on your wristwatch or something.
