  10 macros used:
  11
  12 BOOST_CLBL_TRTS_INCLUDE_TRANSACTION_SAFE - the transaction_safe specifier for
  13     the current include (`transaction_safe` or nothing)
  14
  15 BOOST_CLBL_TRTS_IS_TRANSACTION_SAFE - `std::true_type` or `std::false_type`,
  16     tied on whether BOOST_CLBL_TRTS_INCLUDE_TRANSACTION_SAFE is `transaction_safe`
  17
  18 BOOST_CLBL_TRTS_TRANSACTION_SAFE_SPECIFIER - `transaction_safe` when
  19     BOOST_CLBL_TRTS_ENABLE_TRANSACTION_SAFE is enabled, otherwise nothing
  20
  21 BOOST_CLBL_TRTS_NOEXCEPT_SPEC - the noexcept specifier for
  22     the current include (`noexcept` or nothing)
  23
  24 BOOST_CLBL_TRTS_IS_NOEXCEPT - `std::true_type` or `std::false_type`,
  25     tied on whether BOOST_CLBL_TRTS_NOEXCEPT_SPEC is `noexcept`
  26
  27 BOOST_CLBL_TRTS_NOEXCEPT_SPECIFIER - `noexcept` if
  28     BOOST_CLBL_TRTS_ENABLE_NOEXCEPT_TYPES is defined, otherwise nothing
