Remove this guy too?

[Nico, 2016/01/05 17:35:07]

No, this one is needed: pdfium isn't -Wsign-compare clean. The problem was that
build/common.gypi's shenanigans previously made it impossible to disable this
warning on Linux. Now that build/common.gypi doesn't do this anymore, this
warning has an effect and things build.

Removing this flag here will require some code cleanups.

Acknowledged. "some" code cleanups, probably for a large value of "some".
