So, either you're using some other version (please state which), or the code you posted is not the code that generated that warning.

Or option 3: The point of the OP wasn't "why did I get this warning?", but, rather, "I made this mistake and didn't get a warning. Maybe it should issue one?"

Firstly, my apologies for the late reply. I usually log in daily; this week I skipped a couple of days.

I read the quote in the title ("Useless use of a constant") as the message received after making "a stupid mistake"; and the quote in the body ("Probably useless use of a constant ...") as the preferred message.

On rereading, I think you're right and my interpretation was incorrect.
