+// e32test\dll\t_path.cpp
+// Overview:
+// Test imported DLL path search order.
+// API Information:
+// None (implicit searching when loading an executable)
+// Details:
+// - t_pathdll1 and t_pathdll2 both export the same function which returns 1
+// 2 respectively.
+// - Run t_path2 (linked to t_pathdll1) and check return value from DLL - should
+// be 1.
+// - Copy t_pathdll2 to C: and rename to t_pathdll1 - it should now be loaded 
+// instead.
+// - Run t_path2 again and check return value from DLL - should be 2.
+// Platforms/Drives/Compatibility:
+// Not on emulator.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
