It would probably make sense to have a warning in case a Makefile.am has install-*-local rules but no uninstall-local. BTW, I must say I don't really understand why, at least to keep symmetry, all the install-*-local targets are mapped to a single uninstall-local one. That there is one is nice, but I find it clearer to have perfect symmetry btw install/uninstall. Just a remark, not a demand :)
