I cannot uinderstand your reasoning. How can 'info autoconf' incluence the license of the aclocal.m4 file? Or do I misunderstand something?

OK. I now notice I was confused as to why the license issue arose in the first place, but FWIW: My point was just that the autoconf info pages explain (if I read them right) that one keeps one's project-specific autoconf m4 macros in a file named 'aclocal.m4'. It's not a file distributed with autoconf, it's just a file naming convention, so I made the assumption that since libffi is apparently OK to include in Python, so must be its aclocal.m4 (even if some of the macros in the libffi aclocal.m4 originally derived from some other project).

But I'm afraid this would fail with an AssertionError if it weren't pseudocode:

import legally_compatible as compat from autoconf import acfiles from ctypes import libffi

if compat(acfiles, libffi) and compat(libffi, python): assert compat(acfiles, python), "John is not legally competent"

:-(
