+       perror: call strerror_r directly
+       * modules/perror (Files): Drop strerror-impl.h.
+       * lib/perror.c (perror): Use our own stack buffer, rather than
+       calling a wrapper that uses static storage.
+       * doc/posix-functions/perror.texi (perror): Document a limitation
+       of our replacement.
+
        strerror_r: fix includes for FreeBSD
        * lib/strerror_r.c (includes): Use <stdlib.h> unconditionally,
        since we use abort on some platforms.
