+    gdb: Fix ia64 defining TRAP_HWBKPT before including gdb_wait.h
+    
+    On ia64, gdb_wait.h eventually includes siginfo-consts-arch.h, which
+    contains an enum with TRAP_HWBKPT, along with a #define. Thus we cannot
+    define TRAP_HWBKPT to 4 beforehand, and so gdb_wait.h must be included
+    earlier; include it from linux-ptrace.h so it can never come afterwards.
+    
+    gdb/ChangeLog:
+    
+            * nat/linux-ptrace.c: Remove unnecessary reinclusion of
+            gdb_ptrace.h, and move including gdb_wait.h ...
+            * nat/linux-ptrace.h: ... to here.
