I see how the change fixes the issue with existing relative paths, but 
it indicates that OUTPUTDIR is different to CONFIGURE_START_DIR - so 
what happens with generated output now we have a different cwd? Is it 
all controlled by absolute paths and so will still go to the place(s) 
regardless?

Thanks,
David
