That's true. But cygwin DOES behave differently between 1.5 and 1.7 for pthreads, because it was fixing some races. It looks like not all the races were fixed, and that test-tls fails differently for 1.7 than it does for 1.5 (if you force it to run on 1.5). Which means cygwin still has bugs that need fixing. > > What's not clear to me is if Cygwin 1.x for x > 5 is supposed to have > fixed that problem or not. Yes, cygwin 1.7 has intentional patches to fix pthread, and if there is still a bug in 1.7.1, it is hopeful that it can be patched for 1.7.2. -- Don't work too hard, make some time for fun as well!
