That’s because a Gnulib bug that triggers when building against GNU libc
2.16+, fixed by:

  commit 66712c23388e93e5c518ebc8515140fa0c807348

      stdio: don't assume gets any more

      Gnulib intentionally does not have a gets module, and now that C11
      and glibc have dropped it, we should be more proactive about warning
      any user on a platform that still has a declaration of this dangerous
      interface.

      * m4/stdio_h.m4 (gl_STDIO_H, gl_STDIO_H_DEFAULTS): Drop gets
      support.
      * modules/stdio (Makefile.am): Likewise.
      * lib/stdio-read.c (gets): Likewise.
      * tests/test-stdio-c++.cc: Likewise.
      * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Fix comment.
      * lib/stdio.in.h (gets): Make warning occur in more places.
      * doc/posix-functions/gets.texi (gets): Update documentation.
