The small tests I do to verify the newly built g++ works after building gcc 
looks like this:

for bits in 32 64; do
	echo "checking ${bits}bit g++"
	echo -e "#include <iostream>\nint main(int argc, char** 
argv)\n{\n\tstd::cout << \"Hello C++ (${bits}bit)\" << std::endl;\n\treturn 0;
\n}" >hw.cpp
	${PREFIX}/bin/g++-${GCCVERSION} -m${bits} -o hw${bits}g++ hw.cpp 
	./hw${bits}g++
done

It used to work until gcc 4.3.1 which was the last gcc I built (now I am 
trying to build gcc 4.5.1)
