  Revision 1.16  1996/12/15 20:23:08  wenger
  Incremented revision; prints current architecture at startup.

  Revision 1.15  1996/12/03 20:29:57  jussi
  Fixed some AIX problems.

  Revision 1.14  1996/11/21 19:14:09  wenger
  Fixed more compile warnings; updated devise.dali to match current
  command-line flags.

  Revision 1.13  1996/09/26 18:58:31  jussi
  Removed extraneous definition on Alpha/OSF.

  Revision 1.12  1996/09/25 18:36:52  wenger
  Updated again for Linux compile (Linux 2.0.6, Tcl 7.4, Tk 4.0).

  Revision 1.11  1996/07/29 21:40:24  wenger
  Fixed various compile errors and warnings.

  Revision 1.10  1996/07/18 02:16:42  jussi
  Added support for Ultrix.

  Revision 1.9  1996/07/17 00:47:26  jussi
  Added a redefinition of SIG_ERR/SIG_DFL/SIG_IGN on the Ultrix
  platform.

  Revision 1.8  1996/07/13 04:59:45  jussi
  Added conditional for Linux.

  Revision 1.7  1996/05/31 15:41:44  jussi
  Minor change to remove compiler warnings in Linux.

  Revision 1.6  1996/05/20 18:42:03  jussi
  Replaced PENTIUM flag with SOLARIS.

  Revision 1.5  1996/03/27 17:55:11  wenger
  Changes to get DEVise to compile and run on Linux.

  Revision 1.4  1996/03/26 15:35:01  wenger
  Fixed various compile warnings and errors; added 'clean' and
  'mostlyclean' targets to makefiles; changed makefiles so that
  object lists are derived from source lists.

  Revision 1.3  1996/02/15 18:01:10  jussi
  Small fix for ioctl() on AIX.

  Revision 1.2  1996/02/13 16:35:44  jussi
