+ lzw: Count the size of the memory object by ptrdiff_t.
+
+ * src/lzw/ftzopen.h: The types of FT_LzwState->{buf_total,+ stack_size} are changed from FT_UInt to FT_Offset, to match
+ with size_t, which is appropriate type for the object in
+ the memory buffer.
+
+ * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): The types of
+ `old_size' and `new_size' are changed from FT_UInt to
+ FT_Offset, to match with size_t, which is appropriate type
+ for the object in the memory buffer.
