    Problem Summary 32bit depth has been compiled in 64bit depth by mistake in cpypln.m
    Problem Text Turns out that the test program has a bug that only shows up with
    thetarget framebuffer reports 32bit depth and the test is compiled in
    64bitmode where a long is 64 bits and not 32 bits.

    The developer of our team suggest a fix. I attached the fixed test
    module and the code diffs here:

    Review Recommendation Test Suite Deficiency (TSD)
    Review Response This is accepted as a fault in the test suite.

    Note that the submitter's analysis of the problem, and suggested fix,
    are incorrect. The problem is that the line:

    plane = (1<<vp->depth);

    can set plane to 1 (a valid value for plane) on LP64 architectures
    when vp->depth is 32. The line should be:

    plane = (1UL<<vp->depth);
