The macro expands to a function call, not a declaration, so I'm not entirely
sure what this warning means or how to fix it.

What compiler version are you using? Maemo is using and old gcc (3.4), so
this might be  the reason for different behaviour. gcc 4.x is a bit more
strict about the code it accepts. It might also be that we compile with
different compiler flags.

Are you sure this is needed ? I can't reproduce the issue, geography

The paintings puzzle will not load without this patch Maemo.
libshapegame.sowill have an unresolved symbol (
gnome_canvas_polygon_get_type).

Ok, I'll try.

If I remember the scanning is done once but each time we get an activity

Ok, so you think I should remove all the plugins which depend on python from
the gcompris package? Is there an easy way to identify them? The delay I'm
getting is approximately four seconds, so I'd really like to get this out.

Best regards,
Terje
