Nit: Do we actually need to comment out the param name?  I thought we built with
that warning disabled...

The comment in common.gypi that disables the warning has "These warnings are
level 4. They will be slowly removed as code is fixed." above it, so I think
there's an intent to enable it some day.

I'm actually the one on the team working on enabling those warnings, and I have
no intent to ever enable this :)

   return new VersionUpdaterBasic;
