>I can't see how one can implement chdir() to be UNIX-compatible

UNIX chdir doesn't remember the old directory.   Use:

	newdir = Lock(pathname,ACCESS_READ) ;  /* get a lock on the file */
	UnLock(CurrentDir(newdir)) ;           /* change to it, unlock   */
                                               /* the old directory      */

Note you should check to make sure the Lock() succeeded and that 'pathname'
is a directory before you do the Currentdir().

Of course if your application NEEDS to remember the old directory, 
save it yourself.  chdir() shouldn't have to.  It's still a bug in the
Lattice library, however, since they don't UnLock the old directory.
