g++ 3.x gave this warning for statics but not for unnamed namespace globals,
it appears that they fixed it in 4. :-)

You can try applying:

http://boost.cvs.sourceforge.net/boost/boost/boost/bind/placeholders.hpp?r1=1.13&r2=1.14

This is a fix for a problem with g++ precompiled headers, but it should take
care of the warning as well.
