I'm still working on variations of this topic. The problem I am having at
the moment is that a sequence like this, where Bar has a base which is a
%MappedType:

=======
%Module(name=xxx)

%MappedType FooBad
{
%ConvertFromTypeCode
// blah.
%End
%ConvertToTypeCode
// blah.
%End
};

class FooOK
{
public:
    FooOK();
};

class Bar: FooBad
{  <<<<<<<<<<<<<<<< This is line 20
public:
    Bar();
};
=======

gives the error "sip: tmp.sip:20: A class, exception, namespace or mapped
type has already been defined with the same name" but if I change the base
class from FooBad to the non-%MappedType normal class FooOK, it compiles
just fine. I'm on 4.19.4.dev1708081632...have I gone mad?

Thanks, Shaheed
