Hi Daniel, sorry for my taking too long to respond (next time
add [multi_index] --and here possibly [config] too-- so that
I'll be able to notice your post quicker).

This is strange for two reasons:

* MSVC 9.0 is not new and supposedly Boost.Config does already
consider it --and it does not mark BOOST_NO_MEMBER_TEMPLATE_FRIENDS
* Boost.MultiIndex for MSVC 9.0 seems to be running fine,
without any such problem as you report, see column "msvc-9.0" at

http://www.boost.org/development/tests/trunk/developer/multi_index.html

Can you do the following:

1. Compile and run libs/config/test/config_test.cpp (without
your local patch and, if you can afford it, using bjam --if
you can't I guess a manual compile will do also): any
report having to do with BOOST_NO_MEMBER_TEMPLATE_FRIENDS?
2. Can you provide a small, complete test program where the
problem you've observed can be replicated?

Thank you,
