E.g., I recall problems Eli> with it in MinGW. I asked around and learned that std::thread should work fine if you have winpthreads, which apparently is used by default for mingw-w64. I don't actually know much about the mingw world, so I don't know if that is good enough or not. Could you say? Jonathan Wakely also once wrote a port of libstdc++ to the Win32 API, but couldn't find help with testing, so never checked it in. Eli> Same question regarding delivering signals to threads. If the signal thing is broken in this series, then it is probably already broken today. However I think it ought to be ok as SEGV is a synchronous signal; that is, it is delivered to the faulting thread. Does that address your concern here? Tom
