 In this line (boost/context/detail/config.hpp):

 ! defined(__cpp_lib_integer_sequence) && __cpp_lib_integer_sequence <
 201304

 If __cpp_lib_integer_sequence is not defined, then it is zero and checking
 against 201304 is redundant - 0 is less than 201304.

 If __cpp_lib_integer_sequence is defined, then comparinson with 201304 is
 not evaluated because of short-circuiting.

 I think "! defined(__cpp_lib_integer_sequence)" should be removed.
