...uh, he was making a pun.
And besides, unless you're using assembly, porting something to a RISC processor isn't that much different from porting it to any other processor. All you really have to do is make sure your code is endian safe (in other words, be mindful of how you write your code if you do anything somewhat low-level) and...you're good. C is nice like that, interpreted languages -- even better.
