[Of course I >could spend time looking at the source to find out, but time is >in short supply, so I guess I'll just have to stay curious.] Likely it's not starting threads using posix calls (pthread_create) but using Windows ones (CreateThread). That would imply that libusb assumes that a Cygwin compilation means "build for Windows" rather than "built for Linux". Given that it is trying to access usb functionality, maybe that makes sense and it might be a permanent false positive. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
