Please, it will help me prevent the build from stopping in VS.

This happens on the trunk version of boost, from svn, the release 
tarball indeed does not display the message. Actually this only happens 
when building boost as a custom build step in my project's build 
process, from Visual Studio 2008. Building from the command line does 
not display the message. Which might make sense, since the message does 
not follow output redirection anyway.

Maybe cl.exe somehow feels it is invoked from a subprocess of VS, or 
sees some environment variables, and knows how to output the message ?

Thank you,
