Not a big surprise:

   emacs24 -Q --batch -f batch-byte-compile test-case.el 
   In end of data:
   test-case.el:14:1:Warning: the following functions are not known to be
       defined: erc-response.contents, setf, erc-replace-regexp-in-string
   Wrote /home/monnier/tmp/test-case.elc

Emacs-24.3 tries to expand macros more eagerly (i.e. more like the
byte-compiler), so files that fail to byte-compile properly are also
likely to fail that eager macro-expansion.

But do note that the above message is somewhat harmless: when eager
macro-expansion fails, Emacs falls back on macro-expanding lazily as it
has always done.  IOW other than emitting the above message your code
should still work fine.
