I have added these macros to c.h:

Browse Source 
#define HIGHBIT                 (0x80)
        #define IS_HIGHBIT_SET(ch)      ((unsigned char)(ch) & HIGHBIT)

and removed CSIGNBIT and mapped it uses to HIGHBIT.  I have also added
uses for IS_HIGHBIT_SET where appropriate.  This change is
purely for code clarity.
