+#include <e32cmn.h>

+// Call our implementations of memcpy/move/set/clr rather than the ARM supplied
+// ones.
+// 
+// Note that the AEABI switched the order of arg2 and arg3 to save an intruction
+// when calling 'memset' from 'memclr'.
+//
+// Prototypes are:
+//   void __aeabi_memset8(TAny* aTrg, unsigned int aLength, TInt aValue);
+//   void __aeabi_memset4(TAny* aTrg, unsigned int aLength, TInt aValue);
+//   void __aeabi_memset(TAny* aTrg, unsigned int aLength, TInt aValue);
