It seems ATK_STATE_READ_ONLY Requires ATK >= 2.16
And Debian 8 still ships 2.14, and per our dependencies policy https://trac.webkit.org/wiki/WebKitGTK/DependenciesPolicy we still should support the default build there.
Build log failure:
Its not needed to make the feature work with ATK 2.14.
We only need to fix the build, so building WebKitGTK+ on Debian 8 (Jessie) can continue to be possible.
Therefore just #ifdef'ing the code for ATK >= 2.16 is ok.
