commit r16-4424-gec331001eaa1e42c6ff9536fa51aeaf2a1c86a6a Author: Luc Grosheintz <[email protected]> Date: Tue Oct 14 17:16:55 2025 +0200 libstdc++: Remove unused local type alias <format>. After r16-4421-g59cabe08b57a26 the local type alias _String isn't used anymore and therefore causes warnings when building the tests with `-Wall -Wextra`. libstdc++-v3/ChangeLog: * include/std/format (_M_format_range): Remove unused local type alias _String.
