The protection of the macros was referenced in C99, removed in C11, and never specified in any C++ standard. Also, the macros are in the namespace reserved to the implementation (compiler) so the compiler is permitted to choose to inject those names. fixincludes/ChangeLog: 2020-09-17 David Edelsohn <dje....@gmail.com> PR target/97044 * inclhack.def (aix_inttypes): New fix. * fixincl.x: Regenerate. * tests/base/sys/inttypes.h: New file.
