+// but unfortunately Go will not allow cgo in test files, so this is a
+// workaround to allow cgo types to be tested.  This configuration is used
+// because spew itself does not require cgo to run even though it does handle
+// certain cgo types specially.  Rather than forcing all clients to require cgo
+// and an external C compiler just to run the tests, this scheme makes them
+// optional.
