// Revision 1.1  1999/04/05 21:32:34  curt
// Initial revision
//
// Revision 1.5  1999/03/02 01:01:58  curt
// Tweaks for compiling with native SGI compilers.
//
// Revision 1.4  1999/02/26 22:08:13  curt
// Added initial support for native SGI compilers.
//
// Revision 1.3  1999/02/02 20:13:24  curt
// MSVC++ portability changes by Bernie Bright:
//
// Lib/Serial/serial.[ch]xx: Initial Windows support - incomplete.
// Simulator/Astro/stars.cxx: typo? included <stdio> instead of <cstdio>
// Simulator/Cockpit/hud.cxx: Added Standard headers
// Simulator/Cockpit/panel.cxx: Redefinition of default parameter
// Simulator/Flight/flight.cxx: Replaced cout with FG_LOG.  Deleted <stdio.h>
// Simulator/Main/fg_init.cxx:
// Simulator/Main/GLUTmain.cxx:
// Simulator/Main/options.hxx: Shuffled <fg_serial.hxx> dependency
// Simulator/Objects/material.hxx:
// Simulator/Time/timestamp.hxx: VC++ friend kludge
// Simulator/Scenery/tile.[ch]xx: Fixed using std::X declarations
// Simulator/Main/views.hxx: Added a constant
//
// Revision 1.2  1998/11/30 17:15:30  curt
// Having the class destructor close the fd was a bad idea ... especially if you
// ever make a copy of the instance and then subsequently destroy either.
// close_port() is now a separate member function.

// Revision 1.1  1998/11/16 13:53:02  curt
