I agree. Also, we still generate the configure.sh into the source tree even
if the output directory is somewhere else. I always keep my output
directories separate from the source tree. Sometimes my source directory is
even on a read-only share. I would prefer and also expect any temporary
files to be placed in the output directory resp. the current directory, not
in the source tree. Would that be possible?

Thanks and Kind Regards, Thomas
