Thanks for reviewing Makefile.am setup. 
  The reason 'quux.el' (in above example) is not listed, is
that it should not be byte-compiled by some reason. It is
intentionally excluded from the to-be-compiled list. I didn't
get that point. Thanks a lot.  I will either adjust Makefile.am
or pursue not using automake, or insist to depend automake.

With your advice for VPATH issue, I am now using attached patch,
thanks a lot,
