* _ismbcpunct - Test if character is punctuation (MBCS)
*
*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
