/* Revision 1.9  1998/07/12 03:11:04  curt
/* Removed some printf()'s.
/* Fixed the autopilot integration so it should be able to update it's control
/*   positions every time the internal flight model loop is run, and not just
/*   once per rendered frame.
/* Added a routine to do the necessary stuff to force an arbitrary altitude
/*   change.
/* Gave the Navion engine just a tad more power.
/*
 * Revision 1.8  1998/04/21 16:59:39  curt
 * Integrated autopilot.
 * Prepairing for C++ integration.
 *
 * Revision 1.7  1998/02/07 15:29:39  curt
 * Incorporated HUD changes and struct/typedef changes from Charlie Hotchkiss
 * <chotchkiss@namg.us.anritsu.com>
 *
 * Revision 1.6  1998/02/03 23:20:17  curt
 * Lots of little tweaks to fix various consistency problems discovered by
 * Solaris' CC.  Fixed a bug in fg_debug.c with how the fgPrintf() wrapper
 * passed arguments along to the real printf().  Also incorporated HUD changes
 * by Michele America.
 *
 * Revision 1.5  1998/01/19 19:27:05  curt
 * Merged in make system changes from Bob Kuehne <rpk@sgi.com>
 * This should simplify things tremendously.
 *
 * Revision 1.4  1998/01/19 18:40:27  curt
 * Tons of little changes to clean up the code and to remove fatal errors
 * when building with the c++ compiler.
 *
 * Revision 1.3  1997/07/23 21:52:20  curt
 * Put comments around the text after an #endif for increased portability.
 *
 * Revision 1.2  1997/05/29 22:39:59  curt
 * Working on incorporating the LaRCsim flight model.
 *
 * Revision 1.1  1997/05/29 00:09:58  curt
 * Initial Flight Gear revision.
