[Boost-users] BOOST_NO_MEMBER_TEMPLATE_FRIENDS

if the following code is commented out from visualc.hpp the standard streaming operators become available for mersenne_twister - and they seem to work fine. is this a bug or have i just been fortunate in my experimentation? #if _MSC_VER <= 1310 # define BOOST_NO_MEMBER_TEMPLATE_FRIENDS #endif ian whittley
