<iosfwd> also standard for std::string declaration?

[landrum Alfred]

Ok, I just did.  On the Athlon 1800 I'm using, the
difference between including <string> & not is about
300 milliseconds.  Not that much, I admit.  :)

I started looking at this because I noticed how big of
a jump in size the .i's had before & after the
<string> inclusion - about 300k difference.

Hmm.  Well, just for completeness sake, is there a
standard way of getting a string declaration?
