Why isn't GetIconIndex() also found here?

[huangs, 2012/11/14 20:35:55]

Because in the test flow we have

google_chrome_distribution.h
google_chrome_distribution_dummy.cc

GetIconIndex() was not overridden in the .h file, so it's not needed in the
dummy .cc.  However, GetIconFilename() is overridden, so it needs a stub
implementation to prevent link error.  (So no change).
