My project is very big and complicated. I have not been able to produce a simple project with the hints. Embarcadero must have changed something concerning the Inline function because the compiler statement is listed in Delphi 2010 and it does not produce those hints. TMS Grid also produces these hints.
Embarcadero states that you can turn off the hint message.

However, I prefer to just add the unit in the USES clause to satisfy the hint and will do it for each unit that I have source code. It is just a hint which means that it should be be detrimental to my project.
I always try to keep my projects free of hints and warnings (I do not turn them off).
Thanks.
