Sounds good to me. I seriously wonder why an intern __-namespaced macro needs to be portable beyound all currently supported architextures. Maybe we could add another clause to the ? selector and check for sizeof(unsigned long) >= sizeof(const t) to make possible future failures very explicit - but that should IMO be enough. On the other hand, the idea of making this *evil* macro usable by C++ code makes me shiver. Plaese don't tell me bind11 or newer gcc will need this! Martin
