--- Comment #11 from Christopher Albert <albert at tugraz dot at> --- OpenBSD update: cfarm220 (OpenBSD 7.8, amd64) cannot complete a GCC bootstrap build - the system clang crashes on gimple-match compilation (unrelated to this patch). However, pthread_mutexattr_setpshared is confirmed absent on both OpenBSD amd64 and aarch64, so the configure check will correctly disable shmem CAF there as well.
