The fact that one current generally available platform doesn't require the __thread attribute on the extern should be enough to at least question whether an *error* should be diagnosed.

What about the following two sources: char t; --- extern int t; What should happen? According to the C standard this is invalid code but the compiler does not need to diagnose the problem. -- Pinski
