I am using bash and top level configure script is fast without any doubt. but this configure is run as part of gmake invocation at stage 3. It takes around 5-6 hours on my setup to complete libstd++v3 configuration , for some reason. Other parts are running just fine. (Though my machine has just 1 g ram it should still be fine i suppose). -Rohit
