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