HASINLINE is simply a temporary internal compiler define which was  
introduced to indicate that the compiler supports the "inline"  
directive. It is not to be used your own code, since it will be  
removed from the compiler (it even has already been removed from  
2.1.1, and may not even exist anymore in 2.0.4).

I don't think the compiler defines a symbol when inlining is turned  
on. As of 2.1.1, it won't matter anymore either since the compiler  
will always accept the inline specifier, but only actually do  
something with it if inlining is turned on.

That is not about inlining, but about stackframes. Stackframe  
optimization is implemented in 2.1.1 as well.
