4) it is also possible to manually create aliases that are mangled in the old way (va_list as void*) next to the symbols which g++-4.4 will auto-generate. This means some work for the maintainers (and porters) of the directly affected library packages (fortunately, the list of which does not seem to be huge). However, we win: 1) no painful transitions or disturbance on any arch including armel (i.e. it won't be worse than it is now); 2) no massive binNMUs of rdeps; 3) less work for the release team except tracking how affected libraries are being fixed; 4) no extra work for other teams. -- Modestas Vainius <modes...@vainius.eu>
