I think binary based distros (and some of their users) might like this feature as it would allow them to build packages which have fewer hard dependencies but can still use all the libs if they are available and installed about the code, i think it looks ugly, too many #if too many changes interspaced with existing code. Could this be implemeted in a nicer way ? I am thinking here of keeping (almost) all changes outside of existing files [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Those who are too smart to engage in politics are punished by being governed by those who are dumber. -- Plato
