+** Source:  test1.c
+**
+** Purpose: Tests the PAL implementation of the _wtoi function.
+**          Check to ensure that the different ints are handled properly.
+**          Exponents and decimals should be treated as invalid characters,
+**          causing the conversion to quit. Whitespace before the int is valid.
+**          Check would-be octal/hex digits to ensure they're treated no 
+**          differently than other strings.
