** 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.
**
