bug#4845: 23.1.50; Uninterned symbols in .elc files

[Helmut Eller]

In GNU Emacs 23.1.50.1 (i686-pc-linux-gnu, GTK+ Version 2.12.11)
loading a file x.el with contents

 (defmacro foo ()
   (let ((sym (make-symbol "bar")))
     `(progn
        (defun ,sym () (message "function %s called" ',sym))
        (,sym))))
 
 (foo)

works as expected:

 shell> emacs -Q -batch -load x.el
 function bar called

However loading the corresponding compiled file signals an error:

 shell> emacs -Q -batch -eval '(byte-compile-file "x.el")' -load x.elc
 Wrote /tmp/x.elc
 Symbol's function definition is void: bar
 [Exit 255]

There is a #1=#:bar in the constant pool of the compiled function but #1
isn't used at the call site.
