--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:dcc735aaeae1cc985a143ade883db748fb10554d commit r15-1875-gdcc735aaeae1cc985a143ade883db748fb10554d Author: Jonathan Wakely <jwak...@redhat.com> Date: Fri Jul 5 18:39:50 2024 +0100 libstdc++: Restore support for including <name.h> in extern "C" [PR115797] The r15-1857 change means that <type_traits> is included by <cmath> for C++17 and up, which breaks code including <math.h> inside an extern "C" block. Although doing that is not allowed by the C++ standard, there's lots of existing code which incorrectly thinks it's a good idea and so we try to support it. libstdc++-v3/ChangeLog: PR libstdc++/115797 * include/std/type_traits: Ensure "C++" language linkage. * testsuite/17_intro/headers/c++2011/linkage.cc: Replace dg-options with c++11 target selector.
