--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- I'm not opposed to a warning in principle, but I'd prefer it to be one controllable by a -Wxxx option. I don't know how to do that using the preprocessor, so we'd have to do something like: #ifndef _GLIBCXX_NO_CCOMPLEX_WARNING # warning "Including <ccomplex> makes no sense. Define _GLIBCXX_NO_CCOMPLEX_WARNING to disable this warning." #endif And that is a bit ugly.
