[Nano-devel] Is there a minimum version of GCC against which the latest nano can be compiled?

Hi,

I have been building nano packages in my Open Build Service home
project and while it builds fine for CentOS 7, Fedora 24/25,
Scientific Linux 7, it fails to build for CentOS 5, giving the error:

as it builds fine on build systems with newer versions of GCC I am
left asking is this an error caused by how old the GCC I'm using to
build nano is, or is it caused by something that can easily be
patched? I would have reported this at your bug tracker but I thought
it's best to confirm that this is a bug first.

Thanks for your time,
Brenton
