    Problem Text
    The X/Open echo "-n" option semantics are not required by POSIX 1003.2.


    The POSIX spec states

    The following operands shall be supported by the implementation:

    string A string to be written to standard output. If the first
    operand is a "-n" or if any of the operands contain
    a backslash (\) character, the results are
    implementation defined.

    But the X/Open spec states

    The following operands are supported:

    string A string to be written to standard output. If any
    operand is "-n", it will be treated as a string, not
    an option.

    It seems to us that this creats a grey area inthe spec.

    Review Response
    We recommend this request be refused.

    We believe the POSIX.2 and X/Open standards are muitually consistent.

    The POSIX spec defines use of -n as implementation specific.

    The X/Open spec takes advantage of this flexibility in the POSIX
    spec to mandate the -n semantics on XCU compliant platforms.

    If an IUT is being X/Open branded it must conform to the XCU mandated
    behavior.
