I've actually used a compiler where NULL was not 0. Instead it was 0xFFFFFFFF. Presumably this was partially because this the address of the last byte of the reset vector (as well as being the highest addressable byte) and because the erased/unwritten value of a byte of Flash ROM is 0xFF. (At for every Flash ROM device I've ever (directly) used.)
