Hi all, What are your thoughts on bumping the gcc requirement from 4.4 to 4.6? From a syntactic sugar point of view this means e.g. range-based for loops and lambdas (and minor things like constant nullexpr). Most importantly, from a functionality point of view it means fully functional shared_ptr and unique_ptr. In theory these are already there in 4.4, but the standard library implementation is unfortunately broken. The shared_ptr would allow us to completely remove the RefCountingPtr (which is ~8% of the run-time for atomic linux boot). It also means things like std::bind would work properly which should make Nate happy :-).
gcc 4.6 and above has been shipping with most distros for quite some years, and in worst case it should be fairly easy to get on older systems. Ideas, suggestions, thoughts? Is 4.6 ambitious enough?
