Does this patch not compile the newly added files?

[Kevin Bailey, 2016/11/09 16:25:21]

The new files are over in chrome/browser/payments (and
are compiled and tested, of course) so the question
confuses me.

The purpose of this placeholder is so the other directories
can depend on a single stable target, and we can change it
without bothering other owners unnecessarily.
