 # Until autoconf 2.63, handling of the diversion stack required m4_init
 # to be called first; but this does not happen with aclocal.  Wrapping
 # the entire execution in another layer of the diversion stack fixes this.
 # Worse, prior to autoconf 2.62, m4_wrap depended on the underlying m4
 # for whether it was FIFO or LIFO; in order to properly balance with
 # m4_init, we need to undo our push just before anything wrapped within
 # the m4_init body.  The way to ensure this is to wrap both sides of
 # m4_init with a one-shot macro that does the pop at the right time.
