/* Revision 1.9  1998/02/03 23:20:14  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 1.8  1998/01/31 00:43:03  curt
 * Added MetroWorks patches from Carmen Volpe.
 *
 * Revision 1.7  1998/01/27 00:47:51  curt
 * Incorporated Paul Bleisch's <bleisch@chromatic.com> new debug message
 * system and commandline/config file processing code.
 *
 * Revision 1.6  1998/01/19 19:27:01  curt
 * Merged in make system changes from Bob Kuehne <rpk@sgi.com>
 * This should simplify things tremendously.
 *
 * Revision 1.5  1998/01/19 18:40:19  curt
 * Tons of little changes to clean up the code and to remove fatal errors
 * when building with the c++ compiler.

 * Revision 1.4  1997/12/30 20:47:34  curt
 * Integrated new event manager with subsystem initializations.
 *
 * Revision 1.3  1997/12/15 23:54:33  curt
 * Add xgl wrappers for debugging.
 * Generate terrain normals on the fly.
 *
 * Revision 1.2  1997/12/10 22:37:38  curt
 * Prepended "fg" on the name of all global structures that didn't have it yet.
 * i.e. "struct WEATHER {}" became "struct fgWEATHER {}"
 *
 * Revision 1.1  1997/08/29 18:03:20  curt
