Author: Alan Mackenzie <acm@muc.de>
Commit: Alan Mackenzie <acm@muc.de>

    Make lisp/progmodes/js.el dependent on CC Mode in the Makefile.
    
    This will prevent version mismatches between compile time and runtime
    versions.  This fixes bug #43037.
    
    * lisp/Makefile.in: Make js.el dependent on cc-{defs,engine,mode}.elc.
