Because, as noted earlier, it's not reflective of any likely problem in
the user's code. I think a warning is appropriate if the compiler
detects something which might indicate a bug in the application, but
this is just the compiler telling you about that something might go
wrong if you linked with code form a different version of G++. Which is
unlikely, and might go wrong for other reasons too.
