Why?  As said, all those style files use LaTeX-* and TeX-* vars and
functions defined by AUCTeX's core.  However, the style files can't be
required individually, but AUCTeX itself loads them dynamically
depending on the \usepackages and \documentclass you use in your LaTeX
document.  And then it's evident that those vars/functions are defined.

Arg, indeed. :-)

Well, AUCTeX releases have a (setq byte-compile-warnings nil) in a
custom lpath.el that's used when byte-compiling anyway.  My intent is
only to get rid of warnings that are actually ok just for the ELPA
builds.
