kdepim-runtime-4.10.0 can not be compiled with gcc 4.4.7. It complains: agents/nepomukfeeder/nepomukfeederagent.cpp:66: error: using 'typename' outside of template line 66 is typedef QSharedPointer< QMultiHash< typename Akonadi::Collection::Id, typename Akonadi::Item::Id> > MultiHashPointer; This has been introduced with commit 1b2444ff93ccd74fd35ed93366ef18157803434e "Stay away from nested event-loops." Reproducible: Always gcc (Gentoo 4.4.7 p1.1, pie-0.4.5) 4.4.7
