Some of the configury will choose values suitable for 10.0+ when there's no version given, which isn't much tested. There are also two places that explicitly mention 'apple' (I doubt they are important here - and I have a patch to remove them, but for now...) * I'm not sure what --with-__thread is going to do here. * how about a build --enable-checking=yes[,rtf,tree] ? in case that shows something useful? hopefully, will find time to boot a system over the weekend.
