Thanks for reporting that; I installed the attached.

That's probably due to differing versions of Autoconf. It shouldn't 
matter for Emacs since Emacs doesn't use CXXCPP.

It is annoying that this difference would occur on different platforms; 
for now, I wouldn't worry about it (or install the change, as it'll just 
be overwritten the next time I do a Gnulib update).

I use Fedora autoconf FWIW.
