HEADER GUARDS INTENTIONALLY OMITTED
DO NOT INCLUDE THIS HEADER DIRECTLY

BOOST_CLBL_TRTS_INCLUDE_QUALIFIERS - the function-level qualifiers for the
    current inclusion (combinations of `const` `volatile` `&` `&&`, or nothing)

BOOST_CLBL_TRTS_INCLUDE_TRANSACTION_SAFE - the transaction_safe specifier for
    the current include (`transaction_safe` or nothing)

BOOST_CLBL_TRTS_IS_TRANSACTION_SAFE - `std::true_type` or `std::false_type`,
    tied on whether BOOST_CLBL_TRTS_INCLUDE_TRANSACTION_SAFE is `transaction_safe`

BOOST_CLBL_TRTS_TRANSACTION_SAFE_SPECIFIER - `transaction_safe` when
    BOOST_CLBL_TRTS_ENABLE_TRANSACTION_SAFE is defined, otherwise nothing

BOOST_CLBL_TRTS_NOEXCEPT_SPEC - the noexcept specifier for
    the current include (`noexcept` or nothing)

BOOST_CLBL_TRTS_IS_NOEXCEPT - `std::true_type` or `std::false_type`,
    tied on whether BOOST_CLBL_TRTS_NOEXCEPT_SPEC is `noexcept`

BOOST_CLBL_TRTS_NOEXCEPT_SPECIFIER - `noexcept` if
    BOOST_CLBL_TRTS_ENABLE_NOEXCEPT_TYPES is defined, otherwise nothing
