custom module loading and compilation

[prj@case.edu (Paul Jarc)]

Hi.  I'm writing a custom module system that avoids the standard
search path and list-of-symbols naming scheme.  Instead of using
use-modules and define-module, I have a roughly similar procedure,
let's call it my-load, that creates a module with make-module and
loads a file into it with primitive-load.  I want to make my-load
automatically available within the modules I load so that they can use
it to load other modules too.  So my-load adds itself to each new
module using module-define! before calling primitive-load.

This works when I run Guile with --no-auto-compile, but with
compilation enabled, I get:
;;; Unbound variable: my-load
How can I make the binding visible to the compiler?

;;main.scm
(define (my-load path-to-macros)
  (let ((new-module (make-module 0 `(,(resolve-interface '(guile))))))
    (module-define! new-module 'my-load my-load)
    (save-module-excursion
      (lambda ()
        (set-current-module new-module)
        (primitive-load path-to-macros)))
    (let ((interface '(my-macro)))
      (for-each (lambda (sym)
                  (module-define! (current-module) sym
                                  (module-ref new-module sym)))
                interface))))
(eval-when (compile load eval)
  (my-load "/path/to/macros1.scm"))
(display (my-macro 5))
(newline)

;;macros1.scm
(eval-when (compile load eval)
  (my-load "/path/to/macros2.scm"))
(display (my-macro 3))
(newline)

;;macros2.scm
(define-syntax my-macro
  (syntax-rules ()
    ((_ x) (+ x x))))
