Yeah, I don't think we should have something like this. GCC 15 works
perfectly fine for me and many others, so this warning will just be
noise for no purpose. If there is a problem you are seeing with GCC 15,
we should address it, not just say amorphously that there may be
incompatibilities. Same goes for any GCC version really.

Cheers,
Nathan
