I think I would prefer a non-static function:
  bool EqualsIgnoringRef(const GURL& other) const;
I think this is the typical form for non-operator comparison functions we use
elsewhere in the code (I think GURL had one before operator overloading was
allowed by the style guide).

Done.

   // any memory allocations.
   void Swap(GURL* other);
