We should permit individual libraries to target only very recent compilers, if the library author so chooses and there is good reason.
I think this is the case with boost.lockfree. It is not easy to implement it without atomics, and there are no atomics for the C++03 (yet).
I already suggested that Tim add Lockfree to trunk with only C++11 support, so you're arguing against the wind, I guess.
And thus begins the downfall.
at one point, library authors will want to use c++11 language features which cannot be emulated like lambdas? of course we could use c++03 forever ...
one way could be to provide a c++11-only version of boost (boost), which includes c++11 libraries and possibly strips all boost libraries, which have been included in c++11?
One library will start to depend on Lockfree, and soon it's all a right mess of trying to get anything to work on a perfectly conformant C++03 compiler.
iac, will try to add lockfree to trunk this weekend
I just turned on a Linux and Darwin clang trunk c++0x build. Hope that helps. -- Noel
