--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
works fine on x86_64.  Note your testcase doesn't compile and is likely
optimized to nothing (you don't use 'res').  I've fixed it to

typedef __SIZE_TYPE__ size_t;
size_t strnlen(const char * s, size_t count)  
{
      const char *sc;

          for (sc = s; count-- && *sc != '\0'; ++sc)
                    /* nothing */;
              return sc - s;
}

int main()
{
  signed int prec = -1;
  size_t res=0;
  char* str = "mordy";
  res = strnlen(str, prec);
  return res;
}

note also that GCC 4.8 is no longer supported so please try a more recent
version
(preferably 5.3).
