Is the $^M variable available under MacPerl?

       $^M     By default, running out of memory it is not
               trappable.  However, if compiled for this, Perl
               may use the contents of $^M as an emergency pool
               after die()ing with this message.  Suppose that
               your Perl were compiled with -DPERL_EMERGENCY_SBRK
               and used Perl's malloc.  Then

                   $^M = 'a' x (1<<16);

               would allocate a 64K buffer for use when in
               emergency.  See the INSTALL file for information
               on how to enable this option.
