[Larceny-users] R6RS char=?

[Ray Racine]

R6RS 11.11  shows

(char=? char1 char2 char3 ...)    procedure 
(char<? char1 char2 char3 ...)    procedure 
(char>? char1 char2 char3 ...)    procedure 
(char<=? char1 char2 char3 ...)    procedure 
(char>=? char1 char2 char3 ...)    procedure 

But I can't seem to find them in the 
lib/R6RS/r6rs-standard-libraries.sch

char? and the char-cixx? are there in (r6rs unicode)

but no-can-find char=? and friends from R6RS 11.11

Where did they go?

Thanks,

Ray
