+commit df15887584f0025e7b188e408dd3c9f638d68518
+Author: Dan McGee <dan@archlinux.org>
+Date:   Tue Nov 2 18:43:00 2010 -0500
+
+    Fix type-punning issues exposed with GCC 4.5.1
+    
+    The errors below are due to pointer magic that isn't allowed if following C
+    strict-aliasing rules:
+    
+        memcached.c: In function .complete_incr_bin.:
+        memcached.c:1023:16: error: dereferencing type-punned pointer will break
+        strict-aliasing rules
+        memcached.c:1044:13: error: dereferencing type-punned pointer will break
+        strict-aliasing rules
+        memcached.c:1061:17: error: dereferencing type-punned pointer will break
+        strict-aliasing rules
+    
+    Fix this by introducing a union type that allows access to the uint64_t
+    member as necessary, but doesn't add any additional length to the structure.
+    The size remains the same before and after; the only difference is explict
+    casts are now refactored into union member accesses and all compilers should
+    be happy.
