Is this needed? I would have thought that _views.cc files were not compiled in
if TOOLKIT_VIEWS is not defined.

Done.

BTW, I don't like bools that much for things like this - better to have an enum:

enum DisplayCreateProfilePrompt {
  PROMPT_TO_CREATE_PROFILE,
  DO_NOT_PROMPT_TO_CREATE_PROFILE
}

which makes it easier to parse when reading the code (i.e. when you see
Show(true) you don't have to go look up the definition of Show() to know what
|true| means.

[dconnelly, 2013/05/13 14:45:21]

Done.

+      FindBrowserWithProfile(profile_, chrome::GetActiveDesktop());

[Andrew T Wilson (Slow), 2013/05/08 14:23:48]

This is possibly OK, although I suspect it might break inappropriately if the
user switches desktops while signing in?

Perhaps if we can't find a browser, we should create one? Also consider either
passing in a Browser (tricky, because you may need to listen for that browser
getting closed), or passing in a desktop instead of using
chrome::GetActiveDesktop() since the caller knows what browser/desktop should be
used.

[dconnelly, 2013/05/13 14:45:21]

Done.  Browser now passed by the caller.

Consider just Reset()-ing the callbacks once you've called one instead of
keeping a responded flag. It's more fail-safe, and also probably clearer as to
your intent.

What does it mean if source != link? Is this possible?
