It doesn't seem to produce a warning for the system's/glibc's wait() definition, even though there is no __extension__ on that. I guess that's special-handling for system headers(?) (Either way our target language is "C with gcc/clang/icc common extensions", so I guess -pedantic is not appropriate...)
