--- Comment #6 from CVS 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:2a23b93f944fa78d4284eb5687051c224e5ab08f commit r13-4528-g2a23b93f944fa78d4284eb5687051c224e5ab08f Author: Jonathan Wakely <jwak...@redhat.com> Date: Mon Dec 5 21:44:26 2022 +0000 libstdc++: Fix test that fails due to name clash with old glibc [PR107979] This test was recently modified to check that the library doesn't use __unused anywhere, because that's a macro in newlib. But it's also a macro in old versions of glibc, so the test now fails for those targets. Disable that check for those targets as well as for newlib. libstdc++-v3/ChangeLog: PR libstdc++/107979 * testsuite/17_intro/names.cc: Do not check __unused on old Glibc versions.
