commit r17-5283-g014a57330d1f5d8a6eb97afac2b2aff797241f6d Author: Sam James <[email protected]> Date: Sun Oct 11 19:45:55 2026 +0100 libcc1: use AC_CONFIG_HEADERS, not obsolete AC_CONFIG_HEADER sourceware's builder.git has autoregen.py but it looks for AC_CONFIG_HEADERS, not AC_CONFIG_HEADER. I've sent a patch to fix that too. This caused issues before w/ missed regens (r16-5820-gde867059a0fffe). libcc1/ChangeLog: PR bootstrap/103459 * configure.ac: Use AC_CONFIG_HEADERS, not AC_CONFIG_HEADER.
