#+TITLE: Native-comp macro-defining macro bug
Hi Andrea, et al,
This provides a way to reproduce a bug I seem to have found in the
native-comp feature in this Emacs version:
: GNU Emacs 28.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version
3.24.5, cairo version 1.16.0) of 2021-09-06
The function ~emacs-lisp-native-compile-and-load~ does not seem to
ensure that macros defined in a ~require~'d file are defined before
compiling the current buffer.
* Steps to reproduce
1. In an empty directory:
a. Make file =foo.el= with these contents:
(defmacro foo-define-definer (name prefix)
`(defmacro ,name (name args &rest body)
(let ((function-name (intern (concat ,prefix "-" (symbol-name name)))))
`(defun ,function-name ,args ,@body))))
b. Make file =bar.el= with these contents:
(foo-define-definer bar-define-key "bar-key")
(bar-define-key baz (&rest args)
(message "%S" args))
2. ~(push default-directory load-path)~.
3. ~(find-file "bar.el")~.
4. =M-x emacs-lisp-native-compile-and-load RET=.
+ Compilation succeeds without errors or warnings.
+ Macro ~bar-define-key~ is defined.
+ Function ~bar-key-baz~ is defined.
*Actual results:* Neither the macro nor the function are defined, and
these warnings are displayed in =*Compile-Log*=:

In end of data:

bar.el:5:2: Warning: the function ‘bar-define-key’ is not known to be defined.

* Additional notes
+ If ~emacs-lisp-byte-compile-and-load~ is called before
~emacs-lisp-native-compile-and-load~, the native compilation succeeds
without errors or warnings, and the macro and function are defined.
