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.
but seems to be triggering a bug.
light.cxx: Added code to adjust fog color based on sunrise/sunset effects
and view orientation. This is an attempt to match the fog color to the
sky color in the center of the screen. You see discrepancies at the
edges, but what else can be done?
sunpos.cxx: Caculate local direction to sun here. (what compass direction
do we need to face to point directly at sun)
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.
on a wider variety of platforms.
Added the declaration of memmove needed by the stl which apparently
solaris only defines for cc compilations and not for c++ (__STDC__)
