Matías,

Line 97 of boost/bimap/relation/support/member_with_tag.hpp, which is
the one where GCC 3.4.x stumbles upon, reads:

template< class Relation >
struct member_with_tag
<
    BOOST_DEDUCED_TYPENAME member_at::info, Relation, void  // line 97
>
{
...

I think the problem is that BOOST_DEDUCED_TYPENAME shouldn't be there as
member_at::info does not depend on Relation. In fact, you've got other similar
specializations at the same file all of which do not have BOOST_DEDUCED_TYPENAME.
