Unfortunately it doesn't seem to be quite enough:

https://autobuilder.yoctoproject.org/typhoon/api/v2/logs/461993/raw
(from centos 7)

| ../../vte-0.56.1/src/utf8-test.cc:27:22: error: ‘literals’ is not a
namespace-name
|  using namespace std::literals;
|                       ^

and:

(from debian9)

m_plain; }

Unfortunately I merged the upgrade into master as we'd had green builds
before this (chance meant we didn't hit this failure) so this is a more
pressing problem now...

Cheers,

Richard
