I see the problem on Ubuntu 18.04.3 LTS which has GNU texinfo 6.5 and TeX Live 
2017/Debian. It's due to a bug in libmicrohttpd.texi that is unrelated to 
Gnulib's gpl-2.0.texi. If I install the attached patch, "make dvi" outputs the 
following diagnostics. I suggest getting an appropriate texinfo and TeX Live to 
debug this.
