I'd suggest to make this a function, e.g. on subr.el or perhaps
frame.el, in case some day this test needs to be modified, in which
case we do not want to go through dozens of places that use it.

FWIW, these changes are fine with me, but:

 . I think the manual and NEWS should mention it.

 . Please make sure it does TRT on systems that don't support
   start-process (say "M-: (fmakunbound 'start-process) RET" and see
   that "M-x compile" still works as you'd expect).

Thanks.
