Bruno already explained why it is not a good idea to let DESTDIR be the indicator of whether to look in /usr or not. But I agree with you that there *should* be a common indicator to turn off looking in /usr. I think it should be a generalization of the recent --with-sysroot addition to Libtool (which stems from the much older sysroot support in GCC). Implementors please talk to Paolo Bonzini about further ideas for this. Thanks, Ralf
