Subject: [PATCH] Get this braindead, mongoloid shell look in /stand for pwd if
 it can't find it in /bin.  This is something of a kludge, I know, but
 consider my limited alternatives:  I can't make this an execvp() without
 making people scream that I introduced a failure point or slowed down pwd,
 and I can't make it an optional macro since crunch doesn't let you pass
 arbitrary command-line args to the build of one of its crunch-ees. This is
 the simplest, if not the nicest looking, solution I could come up with.
