// Jon said: "Static linking for runtime is actually the default (even if there is a dll). no_dll means you can't call it at compile-time because a dll is necessary for the compiler to load."
// The lib that is created with the DLL is
// just a stub lib. If you want static linking without any need for a DLL then
// build an actual static lib and use #library,no_static_library
// @incomplete I'm probably doing something wrong below, so review the above and play around with it.
