Mmmm, it doesn't work with HAVE_WORKING_VFORK, but it does with
HAVE_WORKING_FORK.  It seems vfork is only used for daemonizing itself,
and not for the few other needs to fork vtun has.

It is strange, the configure script does not try to see if fork or vfork
works, it seems the fact that it is working has to be provided
manually.  It is a problem because it won't run any script or daemonize
itself if it can't fork...
