The goal is not to solve any particular problem (other than the "find the
maximum of a list of numbers" problem shown above), but rather to understand
how the various implementations (of the variable args functionality) work.

What I'd like to see is an implementation of the max() function that doesn't
require a 0 to be passed to signal the end of the list (and, consequently,
has the limitation that 0 can't be a valid data point).

But thanks for the note about vprintf - this seems to imply that there
should be wrapper functions provided by the system for any "standard"
functions that take variable numbers of args.  I note that there is a
vscanf; are there any other standard functions that take variable numbers of
args?  (I can't think of any off hand, but I haven't tried very hard...)
