   unsigned HOST_WIDE_INT min_size = 0;
-  unsigned HOST_WIDE_INT max_size = -1;
-  unsigned HOST_WIDE_INT probable_max_size = -1;
+  unsigned HOST_WIDE_INT max_size = HOST_WIDE_INT_M1U;
+  unsigned HOST_WIDE_INT probable_max_size = HOST_WIDE_INT_M1U;

For consistency, you can use HOST_WIDE_INT_0U for min_size as well.

OK with the above addition.

Thanks,
Uros.
