    25 // the following help macro is to guarentee that certain coded
    26 // is not removed by over-eager linker optimiser.  In certain cases
    27 // we create static objects must be created but are actually never
    28 // referenced - creation has a side-effect such as global registration
    29 // which is important to us. We make an effort to refer these objects
    30 // so that a smart linker won't remove them as being unreferenced.
    31 // In microsoft compilers, inlining the code that does the referring
    32 // means the code gets lost and the static object is not included
    33 // in the library and hence never registered.  This manifests itself
    34 // in an ungraceful crash at runtime when (and only when) built in
    35 // release mode.
