/***
* _ismbclower - Test if character is lower case (MBCS)
*
*Purpose:
*       Test if the supplied character is lower case 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 character is lower case, else FALSE
*
*Exceptions:
*
