[banshee] [build] Started IntPtr ctor verification tool

    [build] Started IntPtr ctor verification tool
    
    Exposes types derived from GLib.Object that do not implement a protected
    or public constructor accepting a single IntPtr as a parameter. Still
    needs to verify that matching constructors chain up to the matching base
    constructor.
