** 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
**
