bug#1719: 23.0.60; Does rx (eval FORM) interfere with byte compiling?

["Lennart Borgman (gmail)" <lennart.borgman@gmail.com>]

I believe that rx (eval FORM) interferes with byte compiling. The
following code gives an error like this during byte compilation:

  nxhtml-js.el:118:8:Error: Symbol's value as variable is void:
nxhtml-smoothgallery-mark

(defconst nxhtml-smoothgallery-mark "<!-- SmoothGallery -->")
(defun nxhtml-smoothgallery-find ()
  (save-excursion
    (save-restriction
      (widen)
      (goto-char (point-min))
      (when  (search-forward nxhtml-smoothgallery-mark nil t)
        (back-to-indentation)
        (when (looking-at (rx
                           "<div id=\""
                           (submatch
                            (1+ (not (any ">")))
                            )
                           "\">" (eval nxhtml-smoothgallery-mark)
                           ))
          (cons
           (copy-marker (match-beginning 0))
           (buffer-substring-no-properties
           (match-beginning 1) (match-end 1))))))))
