Portability consists, among other things, of machine-to-machine and
compiler-to-compiler portability. Just because your code is dedicated
to one machine, be it a PC or a network controller, doesn't mean you
want to re-write it when your vendor "upgrades" their non-standard
features out of existence, or when the computer your cross-compiler
runs on becomes obsolete and you have to get a different system.
