Excuse me, but this is total rubbish.  Arguments *shorter* than "int" are
widened to "int" - NOT "long" - when passed to a function.  "int" arguments
are left alone.

"%d" will NOT work for "long" arguments on a machine where "int" and "long"
are not the same size.  %d is NOT meant for "long"s, it is meant for "int"s.
"%ld" is what you must use for "long"s.
