+** Source:  SetFileAttributesA.c
+**
+**
+** Purpose: Tests the PAL implementation of the SetFileAttributesA function
+** Check that using two flags (READONLY and NORMAL) only sets the file
+** as READONLY, as MSDN notes that everything else overrides NORMAL.
+**
+** Depends:
+**        CreateFileA
+**        CloseHandle
