  $Log: bunxtype.inc,v $
  Revision 1.7  2004/01/04 20:08:45  jonas
    * moved SIG_MAXSIG and wordsinsigset constants from bunxtype.inc to
      ptypes.inc (already there for Darwin)

  Revision 1.6  2003/11/30 12:40:29  marco
   * fix from sebastian

  Revision 1.5  2003/11/19 17:11:40  marco
   * termio unit

  Revision 1.4  2003/09/14 20:15:01  marco
   * Unix reform stage two. Remove all calls from Unix that exist in Baseunix.

  Revision 1.3  2003/08/21 22:23:34  olle
    - removed parameter from fpc_iocheck

  Revision 1.2  2003/06/01 16:35:27  marco
   * Several small fixes to harmonize the *BSD rtls and Linux.

  Revision 1.1  2003/01/03 15:45:21  marco
   * Renamed to bunxtype.inc (from osposixh.inc), some minor changes
      (as introduced going from posix unit to baseunix)

  Revision 1.6  2002/10/27 17:21:29  marco
   * Only "difficult" functions + execvp + termios + rewinddir left to do

  Revision 1.5  2002/10/27 11:58:30  marco
   * Modifications from Saturday.

  Revision 1.4  2002/09/07 16:01:17  peter
    * old logs removed and tabs fixed

  Revision 1.3  2002/08/21 07:03:16  marco
   * Fixes from Tuesday.

  Revision 1.2  2002/08/19 12:29:11  marco
   * First working POSIX *BSD system unit.

  Revision 1.1  2002/08/03 19:34:19  marco
   * Initial *BSD versions. Seems that OpenBSD doesn't need much change,
      NetBSD may need some fixes to stat record and ftruncate and lseek.
      It is all close together, and it should be doable to have just one copy
      of these for *BSD.
