[wxMac] fix for app.cpp when using wx in embedded situations

[Chad Wagner]

Thanks Stefan, I was having issues with that as well.  Is it changed  
in the downloadable tar of wxMac, or do I need to go to CVS?

I have another issue which may be related.  When I unload I call  
wxEntryCleanup, which calls wxClassInfo::CleanUp, but then if I load  
the plugin again while the host app is still running, it doesn't  
reload the library file (it is already in memory) so the static  
initialization e.g. IMPLEMENT_CLASS macros are not performed, and I'm  
left with a null wxClassInfo::sm_classTable.  Conceptually, the  
problem seems to be that wxEntryCleanup is undoing more than  
wxEntryStart had done.  Is there a way for me to force the host app  
to re-source the library, or another wx function I can call to  
rebuild the class info?  Otherwise I'm stuck with the sloppy option  
of not deleting it on exit.

Thanks,
Chad
