--- Comment #15 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-16 branch has been updated by Jonathan Wakely <[email protected]>: https://gcc.gnu.org/g:7f84e9af923261f3fdd7f15b064c449b7d4157b9 commit r16-9547-g7f84e9af923261f3fdd7f15b064c449b7d4157b9 Author: Jonathan Wakely <[email protected]> Date: Wed Jul 29 16:55:39 2026 +0100 libstdc++: Fix grep for linker warning about --gc-sections [PR126452] Current versions of GNU ld print "warning" with a lowercase 'w' so adjust the grep patter. Also use LC_ALL=C to ensure the warning isn't translated. Because m4 uses square brackets as quotes, we need to use double brackets in the grep pattern to expand to "[Ww]" in the configure script. libstdc++-v3/ChangeLog: PR libstdc++/126452 * acinclude.m4 (GLIBCXX_CHECK_LINKER_FEATURES): Use LC_ALL_C and match both "Warning" and "warning" in ld output. * configure: Regenerate.
