Update of /d9/projects/walkthru/util/firewalk
In directory glint:/var/tmp/luka/walkthru/util/firewalk

Modified Files:
	firewalk.cpp 
Log Message:
fix latent multiprocessing dm code (DM_MULTIPROCESS) to at least compile.
and set it to get compiled in by default on irix.
but leave off runtime option by default since the stuff doesn't actually
work. (same bug we were seeing before -- child process segv's in gl lib.)
you can use new option '-mp' to turn mp on at runtime [and see it die].
(updated help output from 'firewalk -' accordingly.)
