Just generating a list of macros could be done in a number of ways:

- autoconf --trace the macro files, grep for public API namespace,
  use an exclusion list like autoconf/tests/mktests.sh does.
- For gnulib, grep the modules/* files for used macros (supposedly
  those are only public ones), continue with an exclusion list.
