Parameter names in declaration and implementation don't mean a thing, it is 
allowed to use different ones. The compiler warning comes from the "const" 
being in one but not in the other. The warning is harmless.

That's the reason for the warning, but has nothing to do with exportability.

In our case, symbols are exported only by names. Parameter, not parameter or 
const parameter has no influence here. There are more functions where 
declaration says const, implementation doesn't and they are still exported.
