Description of problem: Some change in 4.1.2-34 seems to cause problems with use of boost::type_traits. The build log at the given URL shows errors of the form "error: static data member 'blah' used, but not defined", where 'blah' tends to be something from boost::type_traits. Version-Release number of selected component (if applicable): 4.1.2-34
Please retry with gcc-4.1.2-35.
I believe bug 408011 is a dup of this, and for me / for bug 408011 -35 fixes this.
I'm still seeing this here: http://koji.fedoraproject.org/koji/getfile?taskID=275216&name=build.log
The PR34094 diagnostics has been reverted in 4.1.2-36 (and on the trunk too).
