 // Description:

 // 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:

 //
