Comment(by Gonzalo Matamala <gonmator@…>):

 I think overloading count() is a wrong fix. The right fix is just adding
 const qualifier.

 The C++ standard declare const() member of map, multimap, set and multi
 set as const [23.3.1, 23.3.2, 23.3.3, 23.3.4]:

 {{{
 size_type count(const key_type& x) const;
 }}}

 Also, the bimap documentation
 ([http://www.boost.org/doc/libs/1_40_0/libs/bimap/doc/html/boost_bimap/reference/set_of_reference.html#boost_bimap.reference.set_of_reference.__multi__set_of_views.set_operations])
 declare count() member of

 {{{
 [multi]set_of as const:
 template< class CompatibleKey >
 size_type count(const key_type & x) const;
 }}}
