I  have added these macros to c.h:

	#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.  Applied patch attached.
