/* A proposal has been issued to add a defect macro in Boost.Config to detect
* this problem with pointers to members as template arguments. While
* the macro gets into the library, we follow our own heuristics in order to
* define BOOST_MULTI_INDEX_MEMBER as a convenient wrapper of member<> and
* member_offset<>
/* BOOST_MULTI_INDEX_MEMBER resolves to member in the normal cases,
* and to member_offset as a workaround in those defective compilers for
* which BOOST_NO_POINTER_TO_MEMBER_TEMPLATE_PARAMETERS is defined.
* This latter defect macro was included in Boost.Config starting from
* Boost 1.32, but we keep some additional checking of our own to
* remain compatible with Boost 1.31.
