+// Bernie Bright writes:
+// I've created some new classes to enable pointers-to-functions and
+// pointers-to-class-methods to be treated like objects. These objects
+// can be registered with fgEVENT_MGR.
+//
+// File "Include/fg_callback.hxx" contains the callback class defns.
+//
+// Modified fgEVENT and fgEVENT_MGR to use the callback classes. Also
+// some minor tweaks to STL usage.
+//
+// Added file "Include/fg_stl_config.h" to deal with STL portability
+// issues. I've added an initial config for egcs (and probably gcc-2.8.x).
+// I don't have access to Visual C++ so I've left that for someone else.
+// This file is influenced by the stl_config.h file delivered with egcs.
+//
+// Added "Include/auto_ptr.hxx" which contains an implementation of the
+// STL auto_ptr class which is not provided in all STL implementations
+// and is needed to use the callback classes.
+//
+// Deleted fgLightUpdate() which was just a wrapper to call
+// fgLIGHT::Update().
+//
+// Modified fg_init.cxx to register two method callbacks in place of the
+// old wrapper functions.
+//
+// Revision 1.7 1998/07/30 23:48:54 curt

+// Wrote access functions for current fgOPTIONS.
+//
+// Revision 1.4 1998/06/12 00:59:52 curt
+// Build only static libraries.
+// Declare memmove/memset for Sloaris.
+// Rewrote fg_time.c routine to get LST start seconds to better handle
+// Solaris, and be easier to port, and understand the GMT vs. local
+// timezone issues.
+//
// Revision 1.3 1998/06/03 00:48:12 curt
// No .h for STL includes.
