Even if you build a thread-safe cygwin, it may not work until the C++ runtime library is built using pthreads. Unfortunately, the pthreads implementation in Cygwin/winsup is not mature enough to build thread safe C++ runtime yet, but that's something I'm going to work on soon. It does work under Mingw when you -mthreads to compile and link (which links in the thread-safe C++ runtime). Regards, Mumit -- Want to unsubscribe from this list?
