I'm opposed to this -- the philosophy behind the manywarnings module is to enable all possible kind of warnings that you can get from gcc and then each project has to disable the warnings that they decide are not worth fixing. That decision has to be different for each project. I believe this is fairly well described in doc/manywarnings.texi. I'm not opposed to create a somewarnings.m4 or similar that filters out some warnings, if you would find that useful. FWIW, I have not had to disable the above flags in any of my projects, and I would want to be informed if I introduce new code that triggers them. /Simon
