@jrabet I believe you should link your account to the Microsoft organization instead of signing the CLA which is for contributors outside Microsoft. |

The original XFG enlightening for _Execute_once tried to be clever by using Context to pass the final callback to the trampoline. Unfortunately, Context is used by InitOnceExecuteOnce itself and having the wrong bits set can result in an error being returned. This PR addresses this by defining a struct which contains the parameter value and callback pointer to pass those to the trampoline.
