Now that the final version has been released, I don't think the warning spam for every compiler update is necessary anymore. Boost builds successfully with the RTM version (except for Locale, which doesn't build at all currently).
MSVC 14 RC doesn't call the constexpr conversion operator in some cases.
It complains:
boost_no_constexpr.ipp(72): error C2051: case expression not constant
MSVC 14 RC currently passes the constexpr tests, but fails to compile Boost if BOOST_NO_CXX11_CONSTEXPR is not defined. Added three tests that clang can compile in C++11 mode, but MSVC cannot.
According to the release notes, the following new language features are supported:
- char16_t, char32_t, and unicode literals
- binary literals
- generic lambdas
All Boost libraries build successfully, all config tests pass, and all projects I compiled worked correctly.

- update the last tested version to suppress the "unknown compiler version" warning spam
- fix a comment still mentioning version 18 instead of 19
- with CTP2, MSVC 14 is now officially 2014, which is now reflected in the comment as with the other versions
The test currently tests not only the compiler's support for user-defined literals, but also its constexpr support, which is only partly implemented in MSVC 14. This change removes the constexpr's that MSVC doesn't like so that the tests pass on MSVC 14 CTP2.
