I have some code that was compiling when the project was set to 10.4 or "Use Base SDK" (I'm not really sure what that means. In my project, Base SDK is set to 10.5). But if I compile it with 10.5 (the Overview menu), it fails in a lot of ways, including issues around ucontext and sigcontext. I'm not able to significantly change this code. It's deep in our custom OS code. Is it just a matter of changing the name of the struct we're referencing or include a different header? This email sent to site_archiver@lists.apple.com
