nit: looks like the convention is enable_arc==1

[khmel1, 2015/11/19 17:11:41]

Actually there are different styles currently in the code:
for example: 

chrome/chrome_browser_chromeos.gypi uses  enable_arc
chrome/browser/ui/BUILD.gn uses both.
components/components_tests.gyp uses both.
and so on.


most uses both defines. IMHO it is better to unify everything
in separate CL.

[elijahtaylor (use chromium), 2015/11/19 17:45:49]

Sorry I was being super nitty and meant "enable_arc==1" (no spaces) instead of
"enable_arc == 1" (with spaces).  I think checking chromeos and enable_arc is
fine and matches a lot of other checks I've seen.
