Undefined functions bug summary

When compiling with (speed 3) (safety 0) (space 0), I get:

; Warning: These functions are undefined:
;   STREAM::%LISTEN STREAM::%READ-CHAR STREAM::%UNREAD-CHAR STREAM- 
LISTEN STREAM-READ-CHAR STREAM-UNREAD-CHAR
;

because of references to: listen read-char unread-char (some with  
stream arguments, some without)

However, the compiled code works fine.
