  | commit gcc-15-3532-g7cebc6384a0a
  | Author: Jason Merrill <jason@redhat.com>
  | Date:   Fri Sep 6 15:28:53 2024 -0400
  | 
  |     c++: exception spec and stdlib specialization
  |     
  |     We were silently accepting the pr65923.C specialization of std::swap with
  |     the wrong exception specification; it should be declared noexcept.  Let's
  |     limit ignoring mismatch with system headers to extern "C" functions so we
  |     get a diagnostic for the C++ library.
