+       * memchr.c: Include <stddef.h>, not <stdlib.h> and <sys/types.h>.
+       (LONG_MAX_32_BITS): Remove.
+       Include <inttypes.h> and <stdint.h> if available.
+       (alignof, UNALIGNEDP): New macro, portable to all C89 hosts.
+       (__memchr): Don't assume unsigned long int is either 4 or 8 bytes;
+       let it be any number of bytes greater than or equal to 4.
+       * memrchr.c: Likewise, with __memrchr.
+
        * md5.h: Include <stdint.h> if HAVE_STDINT_H || _LIBC, not
        ifdef _LIBC.
        (md5_uint32): Use uint32_t if available.  Simplify fallback ifdefs.
