Similarly for lib/warn-on-use.h and lib/arg-nonnull.h.
The difference between build-aux/c++defs.h and lib/c++defs.h is that the former contains a copyright notice - because every file we distribute needs to have a copyright notice -, whereas the latter is literally copied into other .h files and therefore does not have a copyright notice - because it would be possibly legally confusing if a file has two copyright notices before it gets slurped in by the compiler. If we were to distribute also lib/c++defs.h, we would be distributing a file without copyright notice, which we shouldn't do. Likewise for warn-on-use.h and arg-nonnull.h. Bruno
