+Description from upstream repo:

+    Date:   Wed Jan 30 23:53:23 2013 +0100
+
+        Various cleanups to test programs
+        
+         - Patch applied using git am from libzmq commit 5f009e52
+         - tests/test_raw_sock.cpp doesn't exist in zeromq3-x, so that
+           file was manually removed from the patch before 'git am'

+Solution: search and add it via AC_CHECK_LIB when building with
+libunwind, as the backtrace function uses dladdr. This problem

+Subject: [PATCH] Problem: new zmq_poller used by zmq_poll without DRAFTs
+
+Solution: do not define ZMQ_HAVE_POLLER in src/zmq_drafts.h otherwise
+src/zmq.cpp will implement zmq_poll using the new poller classes.
+Same for ZMQ_HAVE_TIMERS, even though it has no internal effect, but
+to be safe against future development.

+Subject: [PATCH] configure.ac: allow user to disable libunwind discovery via
+ --disable-libunwind
+
+on ia64 architecture libunwind comes with gcc. Unfortunately
+libunwind is not directly usable as-is and fails at link time:
+
+```
+    ia64-unknown-linux-gnu-g++ -o perf/.libs/local_lat perf/local_lat.o src/.libs/libzmq.so -lsodium -lrt -lpthread -ldl
+    src/.libs/libzmq.so: undefined reference to `_ULia64_step'
+```
+
+The change adds --{enable,disable}-libunwind flag to control
+automatic dependency. The default is unchanged: use if available.
