There is a practical limit on the length of names because the config 
mechanism uses them for file names. But perhaps we can make them less 
cryptic, and still hold them to a reasonable length, say 32 characters. 
How about:

12345678901234567890123456789012
BOOST_NO_SCOPED_ENUMS             // no enum class
BOOST_NO_RAW_LITERALS             // no raw character or string literals
BOOST_NO_UNICODE_LITERALS         // no Unicode literals
BOOST_NO_CHAR16_CHAR32_TYPES      // no char16_t or char32_t
BOOST_NO_EXPLICIT_CONVERSION_OP   // no explicit operator T()
BOOST_NO_DEFAULT_OR_DELETE_FUNCS  // no = default or = delete functions
BOOST_NO_CONSTEXPR                // no constexpr

Thanks,
