    Problem Text
    This test may fail on implemenations because not all arguments prior
    to the 4th argument are referenced in the format string.

    In From "System Interface and Headers Issue 4, Version 2", page 95,
    paragraph 2 under Descripton:

    The message body is generated from the message and following
    arguments in the same manner as if these were arguments to
    printf()...

    On page 185, the fprintf article, it states:

    When numbered argument specifications are used, specifying the
    Nth argument requires that all of the leading arguments, from
    the first to the (N-1), are specified in the format string

    The format in test 139 is:

    #define FORMAT2 "k$+-n.c = %1$+-7.c,k$+-n.s = %2$+-7.s,k$+-n.lo = %4$+-7.lo"
    ^^^ ^^^ ^^^
    The format in test 146 is:

    #define FORMAT2 "k$#- nc = %1$#- 7c,k$#- ns = %2$#- 7s,k$#- nlo = %4$#- 7lo"
    ^^^ ^^^ ^^^
    Notice the numbered argument specificaton %4$ is used, but %3$ is
    missing. These are not valid printf formats so they cannot be valid
    syslog formats.

    Test Output
    TEST PURPOSE #139
    On a call to void syslog(int priority,
    const char *message, .../* argument */) when message
    contains %k$+-n.?, where k = a positive integer and
    the argument is the kth argument where ? = a type
    conversion character (d, hi, lo, f, e, g, c, s) the
    result shall be equivalent to "%k$+n.?" except that
    it shall be left justified.

    TEST PURPOSE #146
    On a call to void syslog(int priority,
    const char *message, .../* argument */) when message
    contains %k$#- n?, where k = a positive integer and
    the argument is the kth argument where ? = a type

    result shall be equivalent to "%k$#n?" except that
    it shall be left justified and, if the first character
    of a signed conversion result is not a sign, a blank
    shall be prefixed to the result.

    Review Information

    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    We agree this is a test suite deficiency in the test
    suite version(s) listed.

    Since the behavior of the printf is undefined when not all
    arguments prior to the Nth argument are referenced in the format
    string, the last line in the syslog output is similiar but not
    identical to the expected output generated by sprintf().
