//  MACRO:         BOOST_MSVC6_MEMBER_TEMPLATES
//  TITLE:         microsoft member templates
//  DESCRIPTION:   Microsoft Visual C++ 6.0 has enough member
//                 template idiosyncrasies (being polite) that
//                 BOOST_NO_MEMBER_TEMPLATES is defined for this compiler.
//                 BOOST_MSVC6_MEMBER_TEMPLATES is defined to allow
//                 compiler specific workarounds.
