I prefer Frediano's variant. Nobody is forced to use autogen.sh and also I don't think anybody would expect autogen.sh to modify the default configure behaviour. I don't think it's a good idea. For example, on Gentoo, which doesn't care for autogen.sh and runs autotools build automatically, the default behaviour (unless the person writing the ebuild would notice) would be dependent on Catch being present in the system. This can create subtle inconsistencies, which aren't critical in this case, but still unnecessary.
