// 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. | |
