** Source:  test1.c (iswdigit)
**
** Purpose: Tests the PAL implementation of the iswdigit function.
**          Tests the passed parameter to iswdigit for being a 
**          digit ('0' - '9'). Also passes non-digits to make sure
**          iswdigit picks them up. 
**          NOTE: There are three ASCII values that under Windows,
**              iswdigit will return non-zero, indicating a digit. 
**              These values are quite apparently not digits:
**              178, 179, 185. 
**          These are not tested.
