Recently, I ran into a problem compiling org-mode asynchronously with each .el file being compiled in a separate process (via native-compile-async). When I tried to compile org-refile.el in a separate Emacs process (without compiling all other .el files), there was no way for the byte-compiler to know that org-with-wide-buffer is a macro.
As I understand, normally org-mode compiles synchronously with all the .el files being byte-compiled in alphabetic order. Then, (eval-and-compile (require 'org-macs)) from org.el is defined prior compiling all the org-*.el files, which accidentally allow the org-mode to be compiled without any issues. Note that I first reported this to bug-gnu-emacs mail-list , but it seems that absence of (require 'org-macs) is wrong on the org-mode side. Let me know what you think.
