Greetings.
I've received this report from the Debian bug system.
In bug-m4 I was told that this is already fixed in gnulib by this commit:
http://git.savannah.gnu.org/cgit/gnulib.git/commit/?h=841d0dcfa8103235836a1aeb0c1ad657f43ade85
so fixing this would be just a matter of making a new release with updated
files.
BTW: I find a little bit odd that only the left brace is escaped in
the git commit above. Sure, it will remove the warning about the
left brace, but it looks a little bit inconsistent.
I will apply the attached patch to the Debian diffutils package.
Thanks.

Dear Maintainer,
diffutils fails to build from source in unstable/amd64. Looks similar to
https://bugs.debian.org/808917 ?
