As you can see in this bugreport (https://developer.berlios.de/bugs/?func=detailbug&bug_id=8241&group_id=5358) the removing of
'#include "cbplugin.h"' from 'src/sdk/pluginmanager.h' seems to break the compilation of Code::Blocks if precompiled headers are disabled. It probably should be put back in.
PS: The bug report can be closed, too, because it referred to a bug in RC2 that is already fixed in the current revisions.
ah therefor it was needed : FreePluginProc.
I couldn't find it.
Sorry for the trouble, thanks for correcting me !!!
fixed rev 2797
and that bugreport is closed.
