A curious error

Just saw this today. On this line:


  s := #13 + #13;

I get this warning:

[FixInsight Warning] gfCvPost.pas(9287): W510 Values on both sides of the operator are equal

Ignoring the silliness of the code, this is a very strange error. Selecting it, the cursor is positioned on the plus sign, which makes it even stranger. Legacy code.

Sorry, I see this is a duplicate of another post.
