Message 72752 - Python tracker
Why do you think this is a bug in Python? It sounds like a bug in the operating system to me. (actually, it's two bugs - please use separate bug reports in the future: one is that Solaris doesn't implement wchgat, and the other one that it doesn't provide SEM_VALUE_MAX. Neither is a fatal bug, though, since it's just some extension modules that thus fail to build)
