Updated to reflect changes from P0558R1 accepted into C++17.
...
1. Expose value_type and difference_type (where present) to user's code.
2. Prohibit arithmetic operations on pointers to non-object types. In
particular, arithmetic operations such as fetch_add/fetch_sub will no longer
compile for pointers to cv void, pointers to functions and pointers to
non-static class members.
Also, use C++11 <type_traits> when possible instead of Boost.TypeTraits to
reduce dependencies. Cleaned up value_arg_type internal type usage for more
efficient argument passing.

Only use intptr_t when available. Only test integer overflows/underflows for unsigned integers (the behavior is undefined for signed ints anyway). This should silence compiler warnings as well.

Corrected memory ordering of loads. Relaxed loads do not synchronize-with seq_cst stores, which allowed the test to fail. Also removed unnecessary loads that did not contribute to the test robustness and could have reduced it by issuing extra memory fences.

Reworked platform selection, fixed Windows backend.
...
Platform selection now works in two stages. First compiler is tested for
the supported configuration. If that fails, OS is tested. Lastly, if
nothing succeeded, emulation backend is selected.

Adjusted the workaround for ldrexd/strexd instruction problem with register pairs allocation. The problem only affects ARMv6k in Thumb mode, so enable these instructions for ARM mode. Also don't base the decision on the compiler version, it is probably not relevant. Updated lockfree test to reflect the recent changes related to ARM backends.

Added a generic atomic<> implementation based on the new __atomic intrinsics available in gcc 4.7 and clang 3.2. The new implementation adds support for 128-bit atomic. Other implementations updated to employ new macros in Boost.Config for defaulted and deleted functions (this is not complete yet). Fixed padding for the lock pool. Initializing constructor for atomic<> made explicit to avoid ambiguities of different overloads of operator=.
