+// Modifications to incorporate Jon S. Berndts flight model code.
+//
+// Revision 1.20 1999/02/02 20:13:38 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 1.19 1999/02/01 21:33:36 curt
+// Renamed FlightGear/Simulator/Flight to FlightGear/Simulator/FDM since
+// Jon accepted my offer to do this and thought it was a good idea.
+//
+// Revision 1.18 1998/12/11 20:26:30 curt
+// Fixed view frustum culling accuracy bug so we can look out the sides and
+// back without tri-stripes dropping out.
+//
+// Revision 1.17 1998/12/09 18:50:29 curt
+// Converted "class fgVIEW" to "class FGView" and updated to make data
+// members private and make required accessor functions.
+//
+// Revision 1.16 1998/12/05 15:54:25 curt
+// Renamed class fgFLIGHT to class FGState as per request by JSB.
+//
// Revision 1.15 1998/10/16 23:27:56 curt
// C++-ifying.
