Hello,
    In my past posting for tty(1) I inadvertently allowed a bug to get
past me.  Here are the diffs to fix ttyname(3).  The ttyname(3) I posted
will work only because of the way U**X and MINIX set up their directory
structure and where they place their devices.  This fix will check if
the devices are also the same and keep ttyname() honest.
