bug#16494: 24.3.50; $EMACSLOADPATH stopped working

[Sebastian Wiesner]

In Emacs 24.3.50, $EMACSLOADPATH stopped working.

To reproduce, save the following code as `load-path-test.el':

(defun print-path-list (paths)
  (dolist (path paths)
    (princ (concat "  " path))
    (terpri)))

(defun main ()
  (princ "load-path:")
  (terpri)
  (print-path-list load-path)
  (princ "$EMACSLOADPATH")
  (terpri)
  (print-path-list (split-string (getenv "EMACSLOADPATH")
                                 (regexp-quote path-separator))))

Then run it with `EMACSLOADPATH=$HOME:/tmp emacs -Q --batch -l
load-path-test -f main'.  I see the following output:

load-path:

$EMACSLOADPATH
  /Users/swiesner
  /tmp

As you can see, `load-path' is not initialized with the value of
$EMACSLOADPATH, even though the variable is properly exported and known
to the Emacs process.

What am I doing wrong?

This stopped working in r115557, 2013-12-16.
For example,

   bool use_loadpath = !NILP (Vpurify_flag);

is backwards.

Thanks for pointing out this problem.  I think I've fixed it in Emacs 
trunk bzr 116077 and am marking this as done.  If the fix doesn't work 
for you we can reopen the bug report.
