Here it is. Looks like all dependencies are in by now.

If this sticks, I'll probably move linux/clang over soonish too.

Waiting on red trybots.

File build/common.gypi (right):

https://codereview.chromium.org/11316240/diff/8001/build/common.gypi#newcode3250
build/common.gypi:3250: # This warns on using ints as initializers for floats in
I find these comments easier to read and it makes the compiler arguments they’re
attached to more obvious if there’s some vertical whitespace. So, blank line
before this line, and also before 3255.

build/common.gypi:3276: # decltype() instead).

ShowInUninitializedTab fails on mac_asan on a whitespace CL too:

mac_rel just ran at too old an revision. I sent another try job which will
hopefully pick up a revision after the gtest roll.

OK, LGTM (although consider adding the newlines, and maybe file a bug to track
-std=c++11.)
