    Bug 798229 - GncDate::c_formats is being created and destroyed twice...
    
    resulting in a double free crash on every exit.
    
    Exclude by name the obsolete pre-GnuCash 4 modules from being inspected
    so that they don't try to construct and destroy their static variables
    twice.
