- Use correct SetLastError values in GetModuleFileName - Fix wrong return codes in GetModuleFileName - Build the TestLibraryA/TestLibraryB libraries always shared and put them in the test output directory - TestLibraryGetModuleFileName always returned success - Improve TestLibraryGetModuleFileName to also check last error values and insufficient buffer sizes - Change TestLibraryGetProcAddress and TestLibraryLoadLibrary to load the TestLibrary from the test executable's directory
