+This test validates the correct operation of a VariantDir specification
+in avoiding reflection: reflection is the case where the variant_dir is
+located under the corresponding source dir, and trying to use elements
+in the variant_dir as sources for that same build dir.
+
+Test based on bug #1055521 filed by Gary Oberbrunner.
