[webkit-dev] Re: Problems specializing DefaultHash

[Mike Emmel]

A little more info  dom_string.h and dom_string.cpp used to exist  in my old
GtkWebcore port. I can't find them in my  svn checkout and so far I've
not found a definition of DOMString anywhere so I think I might be
partially right on this.
