Is there any plan to improve Boost.Atomic portability? I guess we have 
enough atomic experts in Boost but maybe we'll need to make some "call 
for experts" to support more architectures.

I read from Boost.Atomic documentation that supported platforms are:

- gcc 4.x: i386, x86_64, ppc32, ppc64, armv5, armv6, alpha

- Visual Studio Express 2008/Windows XP, i386

That seems a bit limited unless under "GCC" we have several compilers 
compatible with GCC and MSVC (maybe Intel, Clang, Freescale? etc.).

Maybe some Summer of code projects could help here.
