A few more notes: * As Sergio Gomez points out, the ID 4294967295 isn't random but is 2^32-1. * Configure is now starting to fail on other tests, in exactly the same way: by generating an executable with those IDs that I then can't read, causing the test to fail. Again it seems to be random which test fails and when. -- 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
