 This is not a bug, though the error message is
 somewhat misleading. Gcc 3.0 is much closer 
 to c++ standard then 2.95, so <string> header 
 does not define class string in the global 
 namespace anymore.
 
 Either write 
     typedef std::string StringType;
 or
     using std::string; // just after including <string>

class Test
{
  public:

  typedef int IntType;
  typedef string StringType;
};

Compiling the above test program generates the following incorrect error:

test.cxx:11: ISO C++ forbids declaration of `string' with no type
test.cxx:11: parse error before `;' token

The same code works under gcc 2.95.x.
