*Purpose:
*       Test if the supplied character is punctuation or not.
*       Handles MBCS characters correctly.
*
*       Note:  Use test against 0x00FF instead of _ISLEADBYTE
*       to ensure that we don't call SBCS routine with a two-byte
*       value.
*
*Entry:
*       unsigned int c = character to test
*
*Exit:
*       Returns TRUE if c is an punctuation character; else FALSE
*
*Exceptions:
