Hi all from a boost newbie, Given: Linux RH 8.0 gcc 3.2 BOOST_VERSION 103002 I created a boost app and it compiles and runs however I am getting lots of warnings of the form /usr/lib/boost/boost/iterator_adaptors.hpp:775:43: warning: "BOOST_MSVC" is not defined. What am I not doing correctly? I have both included and not included <boost/config.hpp> and I read (http://www.boost.org/libs/config/config.htm#header) that I should not include this. Thanks, -d
