Woops. And I forgot that when linking cc1, -lstdc++ must obviously be 
specified, otherwise there will obviously be loads of undefined references. 
So in any way, I must be able to specify additional libraries for cc1. Since 
I'm manually modifying the generated Makefile for now, I'm open to any 
suggestion! :)
