    Problem Summary TIN4C.00050 The tests fail on systems where sort -c does not write to stderr when the input is disordered.
    Problem Text
    This is a resubmit of PG4C.00131.

    According to the Commands and Utilities, Issue 5:

    "-c Check that the single input file is ordered as specified by the
    arguments and the collating sequence of the current locale. No
    output is produced; only the exit code is affected."

    The test code:

    CT_STDOUT=out.stdout
    CT_STDERR=out.stderr
    cmd=`OpenTP sort 5 A "Verify sort -c exits with 1 and writes stderr if not sorted."`

    $cmd -c unsorted1.txt > $CT_STDOUT 2> $CT_STDERR
    CT_EXIT_VALUE=$?
    if [ $CT_EXIT_VALUE -ne 1 ]; then
    SetResult $TET_FAIL "Expected exit code = 1; Received $CT_EXIT_VALUE"
    else
    SetResult $TET_PASS
    fi

    if [ -s $CT_STDERR ]; then
    SetResult $TET_PASS
    else
    SetResult $TET_FAIL "Standard error is empty"
    fi

    The failure occurs because $CT_STDERR is not of size > 0. However,
    according to the standard, it should not be size > 0 because no
    output would have been produced.

    Since Base Working Group resolution bwg98-002 has been changed, it is
    not reasonable for the test to expect output to stderr with the -c
    option.

    Review Information

    Review Type TSMA Review

    Completed null
    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    The behaviour of this system is allowed by the revised bwg98-002
    resolution, and so a waiver should be granted.
    Since bwg98-002 mentions the need for an interpretation request to
    be filed (by which I assume it means a POSIX.2 interpretation),
    a Temporary Interpretation is recommended.

    Review Type SA Review
