grr; I always forgot about that step.

Could we commit the generated bindings in CVS ?

We also really need some way to:
1) produce luasetup.h from luasetup.h.in (maybe adding 'wx' prefix to 
both as we discussed time ago): I had to manually change it to exclude 
the contrib wx headers which I do not have installed and wxFontMapper 
(see point #3)

2) fix warnings about non-existing symbols (I get ton of messages like:

./modules/wxbind/include/wxbind.h:127:6: warning: "wxUSE_WAVE" is not 
defined
./../modules/wxbind/include/wxbind.h:328:5: warning: 
"wxLUA_USE_wxCriticalSection" is not defined
./../modules/wxbind/include/wxbind.h:506:5: warning: 
"wxLUA_USE_wxCriticalSectionLocker" is not defined
./../modules/wxbind/include/wxbind.h:919:5: warning: 
"wxLUA_USE_wxCriticalSectionLocker" is not defined
./../modules/wxbind/include/wxbind.h:1038:6: warning: "wxUSE_WAVE" is 
not defined
...

)


3) now compilation stops on my file:

./wxbind/src/gdi.cpp:2289: error: ‘class wxFontMapper’ has no member 
named ‘SetConfig’

this is probably because I use wxCVS.
I see in gdi.i:


%class %noclassinfo wxFontMapper
....
     void SetConfig(wxConfigBase *config = NULL)
...
%endclass

can something like


%class %noclassinfo wxFontMapper
....
     #if !wxCHECK_VERSION(2, 7, 0)
       void SetConfig(wxConfigBase *config = NULL)
     #endif
...
%endclass

be written ?


4) disabling wxFontMapper I now get all the errors in the attached log.
This is because I'm on a 64bit machine.
Is wxbind/src/wx_class.cpp something automatically generated ?
If yes, the wxlua wrapper generator should be changed to output (long) 
casts instead of (int) ones...
