+** Source:  test1.c
+**
+** Purpose: Tests the PAL implementation of the _wfopen function. 
+**          This test simply attempts to open a number of files with
+**          different modes.  It checks to ensure a valid file
+**          pointer is returned.  It doesn't do any checking to
+**          ensure the mode is really what it claims.
