Fixed compilation error on GCC versions prior to 4.5

Browse Source 
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.
