Indeed.  The code in defadvice is (generally) not compiled during
byte-compilation.

A (defvar longlines-mode) doesn't have any long term effect: it only
temporarily tells the byte-compiler to shut up.  This only lasts until the
file is byte-compiled.  If you do further byte-compilation (e.g. of the
advice code or of code output by some macro), the byte-compiler won't
remember that the file where this code originally appeared had a (defvar
longlines-mode).
