    plug-ins: fixing various compilation warnings.
    
    Mostly warnings about wrong types for some function parameters.
    There is still a single warning remaining about ignoring the #pragma
    macro, but I am not sure what to do about this warning. Apparently it is
    something specifically for use with Visual Studio. We don't need this,
    but since the contributor uses it, let's keep it.
