    Problem Text
    According to XPG4 or XPG4.2, both specification mentioned that 'If both
    arguments are zero, an implementation-dependent value is returned and errno
    MAY be set to [EDOM].'

    Since this return value is optional, the test should not expect EDOM.
    Test Output
    /tset/ANSI.os/maths/atan2/T.atan2 2 Failed

    Test Description:
    atan2(), when called with both arguments zero, either
    a. returns zero and sets errno to EDOM;
    b. returns NaN and may set errno to EDOM.

    Test Strategy:
    CALCULATE floating point constants using mlmachar().
    CREATE child
    REASSIGN stderr to /dev/null to avoid error output from maths
    functions.
    VERIFY atan2(0.0, 0.0) either
    a. returns zero and sets errno to EDOM;
    b. returns NaN and may set errno to EDOM.

    Test Information:
    ERRNO VALUES: expected: 33 (EDOM), observed: 0 (NO ERROR)
