Thank you for reporting that!
I've fixed it as you suggest: (note that the URL is not yet valid)

        * mkstemp.m4: Require that the system mkstemp be able to create
        70 temporary files, not just 30.  Tru64 V4.0F's mkstemp function
        would fail after 32.  Reported by Danny Levinson.  Details here:
