To elaborate, what I did is define a new class CppUnit::OStringStream
which can be used in the following way.

    CppUnit::OStringStream ost;
    ost << "@Dummy@" << serialNumber++;
    registerFactory( ost.str(), factory );

The definition of OStringStream is the following.  Any comments?


/* Define CPPUNIT_SSTREAM as a stream with a "std::string str()"
 * method.
 */
#include <string>

#if CPPUNIT_HAVE_SSTREAM
#   include <sstream>
    namespace CppUnit {
	typedef std::ostringstream  OStringStream;
    }
#else 
#if CPPUNIT_HAVE_STRSTREAM
#   include <strstream.h>
    namespace CppUnit {
	class OStringStream : public std::ostrstream 
	{
	public:
	    std::string str()
	    {
		(*this) << '\0';                       // necessary?
		std::string msg(ostrstream::str());
		ostrstream::freeze(false); //unfreeze stream [why?]
		return msg;
	    }
	};
    }
#endif
#endif
