lookup-bug.cc: In member function 'std::ostream&
foo::name_space::dump(std::ostream&) const':
lookup-bug.cc:249: error: no matching function for call to
'mem_fun(std::ostream& (foo::instance_collection_base::*)(std::ostream&)const,
const util::memory::never_ptr<const foo::instance_collection_base>&)'

known to work: gcc-4.0.1 (built likewise)

remarks:
Note that this is not std::mem_fun, but rather, a custom extension for
pointer-classes, defined in namespace util.
In the attached .ii, changing the static member declaration:
    static const never_ptr<const instance_collection_base> null;
to
    static const never_ptr<instance_collection_base> null;
is sufficient to compile successfully.
