 =item Too late for "-%s" option
 
 (X) The #! line (or local equivalent) in a Perl script contains the
-B<-M> or B<-m> option.  This is an error because B<-M> and B<-m> options
+B<-M>, B<-m> or B<-C> option.  This is an error because those options
 are not intended for use inside scripts.  Use the C<use> pragma instead.
