Why do you want to re-run configure - can you get away with just `make'? In principle, almost anything could have changed if you have re-run configure (?). Eg you could in principle be compiling for a different arch now. I'm not sure it's possible to distinguish those cases from cases where nothing has really changed. > It looks like the cause is lib/Makefile which states that several > generated headers in that directory depend on config.status.
