How can the compiler quantify exactly how many times this function will be 
called in the same stack?  How will it know that this won't cause a stack 
overflow?

The register keyword is easy, the compiler can't run out of register space 
and cause an exception.

inline also won't cause unforseen runtime errors.

So I see this as a different issue.
