m4: Change defn processing orderHEADmain

Currently, defn pushes its arguments on the stack in order, which means
they are then processed in reverse order.  POSIX does not specify what
order they are processed in, which arguably suggests that they should be
processed in the order they are listed.  Push them in reverse order so
they will be processed in their original order.  This matches GNU m4.
