There's an '#ifdef linux' on the same code a few lines earlier (in
get_ptrace_tid), which fixes compile here as well:

diff --git a/server/ptrace.c b/server/ptrace.c
index b446de9..92b7db5 100644

 {
+#ifdef linux
     if (thread->unix_tid != -1) return thread->unix_tid;
+#endif
     return thread->unix_pid;
 }

but I'm not sure if that's right or not. Comments welcome.
