+// Implementation note:
+// This test requires identical definitions of Interface and Mock to be

+// them in this header and #including it in gmock_link_test.cc and
+// gmock_link2_test.cc.  Because the symbols generated by the compiler for
+// those constructs must be identical in both translation units,
+// definitions of Interface and Mock tests MUST be kept in the SAME
+// NON-ANONYMOUS namespace in this file.  The test fixture class LinkTest
+// is defined as LinkTest1 in gmock_link_test.cc and as LinkTest2 in
+// gmock_link2_test.cc to avoid producing linker errors.
