is :xi necessary here (as compared with .gyp)?

[tfarina, 2014/06/07 02:38:45]

I don't think so.

In GYP build/linux/system.gyp, x11 already includes xi. 

In GN (build/config/linux/BUILD.gn) x11 config already include Xi

I might be totally wrong about this one too, but it builds locally without
declaring it here.

include_dirs += .. is in gyp, not necessary even with the ../wm stuff above?

[tfarina, 2014/06/07 02:38:45]

after a clobber build, hum, no it does not look necessary.

I think it is GN has this built in (I couldn't find), but of course I might be
plain wrong :/
