These files "magically reappeared" after the conversion from CVS to
Mercurial. The old CVS repository deleted these files but did not
record *when* it deleted these files. The conversion resurrected these
files because they have no history of deletion. These files were
probably deleted before year 1995. The CVS repository begins to record
deletions around 1995.
These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted. There is no way to fix
this, because the CVS repository provides no dates of deletion.

! Two system calls (gtty and stty) in the m68000 tail_mon library
! were not really system calls but they used _ioctl. The m68020 machine
! the table was tested on used real system calls, and we'll use
! them here.
! There were also three calls (ftime, lock and dup2) that were in the
! m68000 library, but were not included in the list of system calls
! for the m68020 that was given to me. We'll include them anyway.
! The original gtty and stty files are included here.
! Note however that the 68000 machine (the Mantra) needs the parameters
! to system calls in registers, while the m68020 machine this table was
! tested on wanted the parameters on the stack
!
! Also read the comments in the signal.s file!
