>Description:
	I am under the impression that gcc3's c++ front end is supposed to
	automatically add /usr/include/g++/backward in the include path,
	allowing access to deprecated features by default.
	This does not seem to be the case.
>How-To-Repeat:
	try compiling the following,
	#include <iostream.h>
	int main(int argc, char **argv)
	{
	  std::cout << "Hello world" << std::endl;
	}

	I believe that this should result in a warning about the use of
	deprecated headers, not an error.
	
	Without this feature, a lot of c++ code in pkgsrc will not compile.

>Fix:
	Configure c++ frontend to include /usr/include/g++/backward by
	default.  I think this means defining GPLUSPLUS_BACKWARD_INCLUDE_DIR.
	(I'm not sure about how this is done exactly but it is probably
	done in the reach over makefiles).
