	error byte compiling (defvar :foo ':foo), regression from 23.4
Date: Tue, 10 Jul 2012 19:16:47 -0400

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

Create a new directory and within this directory create the following
two files:

File foo.el:

[foo.el (application/emacs-lisp, inline)]

[Message part 3 (text/plain, inline)]

File bar.el:

[bar.el (application/emacs-lisp, inline)]

[Message part 5 (text/plain, inline)]

From within that directory, run the following command:

  emacs --no-site-file --no-init-file --batch --eval='(setq load-path (cons "." load-path) )' -f batch-byte-compile *.el

Then, again run the same command:

  emacs --no-site-file --no-init-file --batch --eval='(setq load-path (cons "." load-path) )' -f batch-byte-compile *.el

This first time around, both files complain without error.  The second
time I get the following error:

  In toplevel form:
  bar.el:1:1:Error: Constant symbol `:foo' specified in defvar
  Wrote /tmp/baz/foo.elc

I have verified that this is a regression from emacs 23.4.
