Shouldn't these be added by default now then?

Ooo, good catch. I had thought that they might already be pulled in by other
targets, but I suspect you're
right and they aren't. I will add them in and see.

[kjellander_chromium, 2016/02/22 05:26:51]

Just to be clear: I didn't analyze if they were, but I checked that they weren't
at least present in src/BUILD.gn.
