I wasn't talking about array ARGUMENTS.  sizeof returns the size of an
object when used as a member of an array.  This is not necessarily the
same as the number of bytes needed when used as an argument, due to
possibly different alignment requirements in the two cases.  In fact,
some arguments in some implementations are passed in fast registers!

Not to worry about va_nargs().  It's not useful enough to be worth
the hassle.
