/***
* _ismbcspace - Test is character is whitespace (MBCS)
*
*Purpose:
* Test if the character is a whitespace character.
* Handles MBCS chars 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 character is whitespace, else FALSE
*
*Exceptions:
*
