exit_menu.cxx: Compiler error

[Björn Fischer]

Hi,
compiling the current cvs chechout gave the following compiler error:

--------------------Konfiguration: pingus - Win32 Debug--------------------
Kompilierung läuft...
exit_menu.cxx
C:\CVS\Games\Pingus\src\exit_menu.cxx(42) : error C2352: 
'GUI::SurfaceButton::draw' : Unzulaessiger Aufruf einer nichtstatischen 
Member-Funktion
        c:\cvs\games\pingus\src\gui\surface_button.hxx(50) : Siehe 
Deklaration von 'draw'
Fehler beim Ausführen von cl.exe.

pingus.exe - 1 Fehler, 0 Warnung(en)
-----------------------------------------------

The lines 42 and 67 are concerned ('GUI::SurfaceButton::draw(gc);'). 
Commenting the lines out seems to work. I didn't see anything strange 
after I commented them out. What are they needed for? What would be best 
to do with them?

Greetings

Björn
