You could go look through GCC's source code for a 3DNow! C implementation. If I understand correctly, you simply write C code and the the compiler can take advantage of 3DNow! if you feed it the right switch to tell it to (gcc -m3dnow) You do not manually change your code to support 3DNow!...but I could be wrong.
Anyway, 3DNow! is a little dated; you might be better off with SSE2/SSE3 as they can handle more vector information and I think they can work faster as well on current Athlon 64/X2 and Phenoms than 3DNow!
