** Source:  test1.c (fclose)
**
** Purpose: Tests the PAL implementation of the fclose function. 
**          This test will use fdopen to create a file stream,
**          that will be used to test fclose. fclose will also 
**          be passed a closed file handle to make sure it handle
**          it accordingly.
