And a bunch of similar.
ABSL is included in the s2 archive and is being compiled as part of the build, but the build of ABSL is failing on declarations that I think it itself makes. If I download ABSL source from its github and compile that it builds with no issues so I can't see why it wouldn't build as part of s2.
