We don't usually define macros independently for every compiler version. The actual implementation generally looks like:

#if COMPILER_VERSION < NNN   #define BOOST_NO_FEATURE #endif

which is always the same amount of work regardless of whether it's a positive or negative macro.

This ignores -std=... though.

We also test for BOOST_GCC_CXX11 or __cplusplus to take that into account.
