commit r17-5290-gb3323ba3e1f85b43f1e050e23020d363744c0d5e Author: Sam James <[email protected]> Date: Wed Oct 14 02:09:58 2026 +0100 libgomp: drop leftover AC_HEADER_STDC AC_HEADER_STDC was dropped almost everywhere in r17-5037-ga98718d58c8498 (with some other subdirs handled later in the same series while touching those) but I lost a change for libgomp when rebasing because of r17-1945-gdb890f7a7d30f4 and didn't notice. Drop it here too. libgomp/ChangeLog: PR bootstrap/112422 * configure: Regenerate. * configure.ac: Drop AC_HEADER_STDC.
