Created attachment 43008 [details] the log of the failed module build libreoffice (the current sources from the bootstrap repo) fails to build in the sal repo because "'forward' is not a member of '_STL'". I'm using Linux. The complete build log is attached.
Builds again here - note that master is actively worked on, so expect (infrequent) breakage there - if you need a stable build, please use the libreoffice-3-3-0 / libreoffice-3-3 branch instead.
