--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:4be4888d6bddbcc106efeb19e18c380e7c1d041a commit r10-10214-g4be4888d6bddbcc106efeb19e18c380e7c1d041a Author: Jonathan Wakely <jwak...@redhat.com> Date: Fri Aug 20 14:51:06 2021 +0100 libstdc++: Skip filesystem tests that depend on permissions [PR90787] Tests that depend on filesystem permissions FAIL if run on Windows or as root. Add a helper function to detect those cases, so the tests can skip those checks gracefully.
