If you do so, please put a comment on your private routine to
explain why it's there, so the people maintaining it fifteen years
from now don't tear their hair out trying to discover why you re-
implemented a standard library routine.  Also, please put a note about
it in the documentation for the application.  Your routine may well
be slower on the next machine it gets ported to.
