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.
