My point, which I don't think you addressed in your long explanation, is that there doesn't seem to be any "alternate stack" stuff going on in the Windows code. Therefore, it seems like you could just rely on linux signal handling to get the same level of behavior under Cygwin that you currently get with the library. The problem is that, although configure seems to be ok with a missing sigaltstack function, and some of the code tries to work around its lack, there are still lots of places which assume that if you're on UNIX you must have this function. libaltstack is doing something dangerous by assuming that it knows what Cygwin is doing with SEH. I don't think that it should ever be used on Cygwin in its current incarnation. 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
