These warnings are completely harmless. They were introduced in latest automake (1.9.x, I think) to warn package maintainers that they need to update their .m4 files to remain compatible with future automake versions. If you want, you can find out which packages those .m4 files belong to, and file a bug against each of them (directly to their respective upstream developers, _not_ in Gentoo Bugzilla).
