[Matthew Fidler]

You probably downloaded the version with lexical binding disabled.

Sorry, I should have linked to the version with lexical binding enabled.

Also 24.3 does not exit when the warning occurs (which is another bug, actually)

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

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):

Then I cannot reproduce this, neither with Emacs 24.3 nor with the
latest pretest 24.3.92.  I downloaded ergoemacs-translate.el and
ergoemacs-macros.el from that repository, and I get a clean compile.

Did you try this in a fresh Emacs, e.g. "emacs -batch -f batch-byte-compile"?
