[template-value] Dependent template value parameters

[clib-namespace] C library names in global namespace instead of std

+

Library names from the <c...> headers are in the global namespace +instead of namespace std.

Workaround:  The header boost/config.hpp +will define BOOST_NO_STDC_NAMESPACE. It can be used as follows: +

# ifdef BOOST_NO_STDC_NAMESPACE
+    namespace std { using ::abs; using ::fabs; }
+# endif
+

Because std::size_t and std::ptrdiff_t are so commonly used, the workaround +for these is already provided in boost/config.hpp.
