[Message part 1 (text/plain, inline)]

Yes.  I can reproduce with a fresh emacs.  My build script uses a fresh
emacs but calls it by :

~src/ergoemacs-mode $ make
emacs -Q --batch -L . --eval             \
     "(progn                                \
       (setq byte-compile-error-on-warn t)  \
       (batch-byte-compile))" *.el

It also errors on 24.3:

https://travis-ci.org/ergoemacs/ergoemacs-mode/jobs/29898482


And  also errors on the 24.4 trunk (in ubuntu, I believe):
