Another option is to patch Makefile.in to avoid the dependency on
Autoconf/Automake/Libool + this phase.

This is incorrect (see patch below, which also includes indentation
fixes and minor changes to the description to placate ‘guix lint’.)

Also, could you add a comment stating whether it’s dual-licensing or
just that there’s code in both licenses?

A one-line comment at the top explaining what it does would be great.

Otherwise LGTM.  Could you send an updated patch?

Thanks in advance!
