autoload cl-defstruct constructor?

[Stephen Leake <stephen_leake@stephe-leake.org>]

I have code like:

In ada-core.el:

(defun ada-prj-make-compiler (label)
  (funcall (intern (format "make-%s-compiler" (symbol-name label)))))

where 'label' is a user variable indicating choice of Ada compiler.

In gnat-core.el:

(cl-defstruct (gnat-compiler :include wisi-compiler)
   ...)

In foo-core.el, for another Ada compiler:

(cl-defstruct (foo-compiler :include wisi-compiler)
   ...)

The question is how to arrange autoloads so the correct constructor is
available, without loading the file(s) containing the unneeded one(s).

I tried adding an autoload cookie to the cl-defstruct. That almost
works, but update-directory-autoloads doesn't respect the order implied
by :include, so wisi-compiler is declared in autoloads.el after it is
needed.

Is there a way to influence the order of files included in autoloads
(short of renaming the files so alphabetical is correct)?

I could rename the constructor:

    (:constructor create-gnat-compiler)

and provide an ordinary autoloaded defun:

(defun make-gnat-compiler (...)
   (create-gnat-compiler ...))

But that seems inelegant, and maintaining the arg lists is tedious and
error-prone.

Is there a way to autoload just the created constructor?
