??? Isn't gcc suppose to replace any calls to inlined functions
with the function body. Inlined functions are suppose to be compiler
friendly ways of doing things that previously had to be done with macros.
If their is just one definition for the function, wouldn't this mean that
it was working just like an ordinary function?
