>Description:
string class is not usable, becouse gcc can't compile 
it's own header: <std/sinst.h>
>How-To-Repeat:
try next C++ code

#include<string>

#include<iostream.h>

int main(int, char**)
{
string s;
s="Hello, world\n";
cout << s;
return 0;
}
>Fix:
Replasement for <std/sinst.h> 
(I'l introduce PREPROCESSOR variable  (RSSH_STRING)
, of course we don't need to save origin, so second #else ... #endif
purt and this variable can be removed from fix.
