+Subject: [PATCH 3/8] Fixed compilation error on GCC versions prior to 4.5
+
+The deprecated attribute started accepting an optional string argument
+in GCC version 4.5. Compiling libxml2 with GCC versions prior to that
+would cause compilation errors such as:
+```
+./include/libxml/xmlmemory.h:134: error: wrong number of arguments specified for 'deprecated' attribute
+```
+
+Now the string argument is omitted for older versions of GCC.
