 To add a new enum type

+    0. Make sure that all lines you add are protected with appropriate uconfig guards,
+        such as '#if !UCONFIG_NO_SHOES'.
     1. udbgutil.h:  add  UDBG_UShoeSize to the UDebugEnumType enum before UDBG_ENUM_COUNT
       ( The subsequent steps involve this file, udbgutil.cpp )
     2. Find the marker "Add new enum types above this line"
