Update version.hpp for Boost 1.56.
Merge branch 'develop'
Mark <regex> unusable for all libstdc++ versions

The <regex> header is present but the regex implementation is incomplete and fails with regex_error exceptions in runtime for many valid patterns. So define BOOST_NO_CXX11_HDR_REGEX for it unconditionally.

Merge pull request #15 from MSOpenTech/winrt

Fixing failing test case boost_no_cxx11_hdr_regex.
Add constants for memory models used by gnu "__ATOMIC..." intrinsics.  These
should be supplied by the compiler, but until they are we will define them
here.

Once they are defined in the compiler we will need to start sorting out
compiler versions in cray.hpp
