Use -Wold-style-definition.
This patch makes glibc build with -Wold-style-definition to avoid old-style function definitions creeping back in by accident. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). Also tested build for arm, mips64 and powerpc32. Hopefully there aren't any remaining system-specific files with old-style definitions whose formatting evaded my searches, but if there are, they will be easy to fix. * Makeconfig (+gccwarn-c): Add -Wold-style-definition. * Makefile ($(objpfx)c++-types-check.out): Filter out $(+gccwarn-c) instead of -Wstrict-prototypes.
