    Problem Text
    This test is getting compilation errors because of a circular
    definition problem in the header files. The test in question includes
    the file "DragDrop.h", but the files look like this:

    DragDrop.h
    ----------
    #include <DragC.h>

    DragC.h
    -------
    #include <Xm.h>
    ...
    #define XmDROP_NOOP 0L
    #define XmDROP_MOVE (1L << 0)
    #define XmDROP_COPY (1L << 1)
    #define XmDROP_LINK (1L << 2)

    Xm.h
    ----
    #include <Transfer.h>

    Transfer.h
    ----------
    #include <DragDrop.h> /* Will not have the intended effect */
    /* DragDrop.h is now #ifdef shielded */
    ...
    enum { XmMOVE = XmDROP_MOVE, XmCOPY = XmDROP_COPY,
    XmLINK = XmDROP_LINK, XmOTHER };

    So this enum statement will be reached before the macros are actually
    defined. In fact, this happens if you include any of these files
    without explicitly including Xm.h beforehand.

    Possible solutions:
    1. Change the test case to include Xm.h before attempting to
    include DragDrop.h.
    2. Fix the header files. Change the include dependencies to
    prevent this circle. Kind of a puzzle.
    3. Change DragC.h to define these macros before completing
    the circle:

    DragC.h
    -------
    #define XmDROP_NOOP 0L
    #define XmDROP_MOVE (1L << 0)
    #define XmDROP_COPY (1L << 1)
    #define XmDROP_LINK (1L << 2)
    ...
    #include <Xm.h>
