    Problem Summary pathconf/fpathconf not allowing for "may fail" EINVAL condition.
    Problem Text From SUSv3's pathconf/fpathconf description:

    RETURN VALUE

    If name is an invalid value, both pathconf() and fpathconf()
    shall return -1 and set errno to indicate the error.

    ...

    ERRORS

    The pathconf() function may fail if:

    [EINVAL]
    The implementation does not support an association of the
    variable name with the specified file.

    The -1 return with errno set to EINVAL is saying "The implementation
    does not support Prioritized input or output operations on the specified
    file." The "support an association of the variable name with" above with
    _PC_PRIO_IO can be directly translated to "support Prioritized input or
    output operation on".

    Furthermore, text added to XSH6 2004 edition, page 408, L13261-13262
    (RETURN VALUE section on the [f]pathconf() page):
    If the variable corresonding to name is dependent on an
    unsupported option, the results are unspecified.
    says the test suite should not care because we do not claim to support
    the Prioritized Input and Output option.

    The tests are not allowing for the EINVAL "may fail" condition.
    Test Output
    ****************************************************************************************************************
    /tset/POSIX.os/files/fpathconf/T.fpathconf 33 Failed

    Test Description:
    For UNIX03 and POSIX01 modes:
    When the value of name is _PC_ALLOC_SIZE_MIN,
    _PC_REC_INCR_XFER_SIZE, _PC_REC_MAX_XFER_SIZE,
    _PC_REC_MIN_XFER_SIZE, _PC_REC_XFER_ALIGN, _PC_ASYNC_IO,
    _PC_PRIO_IO or _PC_SYNC_IO, and fildes refers to a regular
    file,
    then fpathconf(fildes, name) either returns a value not
    equal to
    -1, or returns -1 without setting errno.

    Test Strategy:
    CREATE a file using creat().
    SET errno to zero
    IF fpathconf(fd, name) returns -1
    VERIFY that errno is zero

    Test Information:
    fpathconf(fd, _PC_PRIO_IO) on "fpathcf-reg" did not give correct
    results expected: return value != -1
    OR: return value == -1, errno == 0 (NO ERROR)
    observed: return value == -1, errno == 22 (EINVAL)

    Test Description:

    _PC_REC_MIN_XFER_SIZE, _PC_REC_XFER_ALIGN, _PC_ASYNC_IO,
    _PC_PRIO_IO or _PC_SYNC_IO, and path refers to a regular
    file,
    then pathconf(path, name) either returns a value not equal
    to -1,
    or returns -1 without setting errno.

    Test Strategy:
    CREATE a file using creat().
    SET errno to zero
    IF pathconf(file, name) returns -1
    VERIFY that errno is zero

    Test Information:
    pathconf("pathconf-t.49", _PC_PRIO_IO) did not give correct
    results
    expected: return value != -1
    OR: return value == -1, errno == 0 (NO ERROR)
    observed: return value == -1, errno == 22 (EINVAL)
