Chris@16 21 // the following help macro is to guarentee that certain coded
Chris@16 22 // is not removed by over-eager linker optimiser. In certain cases
Chris@16 23 // we create static objects must be created but are actually never
Chris@16 24 // referenced - creation has a side-effect such as global registration
Chris@16 25 // which is important to us. We make an effort to refer these objects
Chris@16 26 // so that a smart linker won't remove them as being unreferenced.
Chris@16 27 // In microsoft compilers, inlining the code that does the referring
Chris@16 28 // means the code gets lost and the static object is not included
Chris@16 29 // in the library and hence never registered. This manifests itself
Chris@16 30 // in an ungraceful crash at runtime when (and only when) built in
Chris@16 31 // release mode.
