[code-eli-git] need to build with c++11

Building with gcc8 is fine.

thx for the report. yep can reproduce, linking this to upstream

[acxz]

submitted a fix upstream, let's give it some time for the developer to see/merge it in so I dont have to patch it.

[acxz]

Since it seems like upstream is not planning on fixing the issue anytime soon, I went ahead and patched it locally. Should be fixed now. @petronny let me know if there are other issues.
