I have just announced the change in 3.4.5 regarding C++11 support and accompanied it with a notice that GCC verion 4.8 is likely to become the minimum version later this calendar year.
As it stands (discussed earlier): * Squid-3.4 needs to build with any GCC 4.0+ version with C++03. * Squid-3.6 will need to build with C++11. * The Squid-3.5 situation is still in limbo and will depend on how long we go before it branches. We have a growing list of items needing C++11 features for simpler implementation. At this point I am going to throw a peg out and say Sept or Oct for starting to use C++11 specific code features. That should still allow us enough time to complete and branch 3.5. But if feature completion takes too long, so be it. Cheers Amos
