hi,
I've been attempting to test Lockfree (while at the same time learning to work with boost from trunk, so bare with me I'm a bit new) using Clang 4.0, the version that will ship with Xcode 4.5. It appears that the preprocessor check is only for gcc. If I change:
#if __cplusplus < 201103L
the preprocessor check is for the c++11 standard. the tests require an implementation of atomic<>, as i don't want to show implementation details in the examples. c++11-compliant compilers will provide a correct implementation of <atomic>, but most implementations that i have seen are not complete yet. once boost.atomic is merged, i will use that instead, but until then, the examples are more for reading than for compiling on your favorite compiler. cheers, tim
