    If sizeof(float) is the same as sizeof(long) for your compiler,
    then the problem is with the compiler trying to cast a float value
    to long/int.  Try this to see if that helps:

    XtSetArg(arg, resource_name, *((long *)&float_value));

    or

    XtSetArg(arg, resource_name, *((int *)&float_value));

    'float' resource was quite a recent feature that didn't exist
    in the early stage of Intrinsics development when Motif
    widgets were designed.
