 The PRINT_ERROR logic looks wrong.
 
 A leading ':' should suppress the message, but:
 
 #define PRINT_ERROR     ((opterr) && ((*options != ':') \
                                       || (IGNORE_FIRST && options[1] != ':')))
 
 
 Maybe:
 
 #define PRINT_ERROR     ((opterr) && !((*options == ':') \
                                       || (IGNORE_FIRST && options[1] == ':')))
