Thanks, looks good now.  And it looks like this is erroring out not when
compiling js.el, but when cc-mode has been natively compiled?

$ make
....
make[2]: Entering directory '/home/larsi/src/emacs/native-compile/lisp'
  ELC      progmodes/js.elc

In toplevel form:
progmodes/js.el:4550:11: Error: Symbol’s function definition is void: cc-bytecomp-is-compiling
make[2]: *** [Makefile:318: progmodes/js.elc] Error 1
make[2]: Leaving directory '/home/larsi/src/emacs/native-compile/lisp'

cc-bytecomp-is-compiling is a defsubst, if that's any clue.  The
following patch fixes the problem, but I'm not sure...  why...

diff --git a/lisp/progmodes/js.el b/lisp/progmodes/js.el
