Will the linker remove the functions from the binary if they are unusued?
If built with -ffunction-sections and --gc-sections,, then the linker can do this sort of thing. Otherwise it can't, but the compiler can. I just tested Mike's code on my ARM compiler to make sure and it happily removed print_eth() when it was not used.
