This is not a new problem, actually.  Even if it didn't happen earlier,
it's not because byte-compiler's warnings have changed, but because
some change either causes a code to be byte-compiled which wasn't before.

My guess is that the changes in advice.el have as a side consequence
that your advice now gets compiled even before info.el is loaded.

Yes, I think we should change bytecomp.el so that those warnings get
output via `message' when we're not byte-compiling a whole file.

Actually, no, it's been there for quite a while.
