+       ignore-value: handle pointer types, too
+       * lib/ignore-value.h (__attribute__): Remove definition.
+       (ignore_value): Remove use of "__attribute__ ((unused))" in favor
+       of a more concise and more-often effective "(void) i" statement.
+       (ignore_ptr): New function to suppress warnings from functions that
+       return pointers, and to make it explicit that one function doesn't
+       handle all cases.
