This error can appear in gdb/nat/linux-ptrace.c because of
the order in which some headers are processed:

A patch from GDB's current master solves the issue.

+Subject: [PATCH] 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.
+
+Upstream-Status: Accepted [https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=5a6c3296a7a90694ad4042f6256f3da6d4fa4ee8]
