9cab8a9ebf 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=.

5b0186dc7d Added implementation of 64-bit atomic operations on 32-bit Windows. Pointer specializations of 64-bit CAS-based atomic implementation extracted to a separate header, since these specializations are not needed on 32-bit platforms.

f9c4249c8e 1. Fixed compilation with MSVC 2003. 
2. Fixed incorrect reinterpret_casts in constexpr constructors that could result in buffer overruns. The initializing constructors for non-integral atomics are not constexpr yet because memcpy must be used inside.
3. Made atomic_flag default constructors constexpr. This is not by the standard but we do not implement ATOMIC_FLAG_INIT yet, so the default constructor is needed and it should be constexpr when possible.
4. Fixed a few syntax errors and cleaned up the code a bit.
5. Moved operator value_type() to the interface class in order not to duplicate it in base_atomic specializations.
6. The return type of operator=() changed to follow the standard.

3870d2bf30 Catch conflicting macro definitions 
Compilation reportedly fails on icc, conflicting macro definitions (both
__i686__ and __x86_64__ defined) is under suspicion. This patch tentatively
fixes the issue.
