    * UCHAR -> HB_UCHAR
    ; NOTE: In cdp subsystem 'unsigned char' is used instead of HB_UCHAR
            in many places, maybe it needs cleanup (I've found 
            one inconsistency in a function declaration).
    ; QUESTION: There is one suspiciously looking usage:
                ftattr.c / iColor = ( HB_UCHAR ) *pAttrib++;
                Is it ok?
