New Revision: 305085

Log:
  Fix warnings in tnftp about invalid constant conversions, e.g.:
  
  contrib/tnftp/src/ftp.c:2067:11: error: implicit conversion from 'int'
  to 'char' changes value from 255 to -1 [-Werror,-Wconstant-conversion]
          buf[0] = IAC;
                 ~ ^~~
  /usr/include/arpa/telnet.h:39:13: note: expanded from macro 'IAC'
  #define IAC     255             /* interpret as command: */
                  ^~~
  contrib/tnftp/src/ftp.c:2068:11: error: implicit conversion from 'int'
  to 'char' changes value from 244 to -12 [-Werror,-Wconstant-conversion]
          buf[1] = IP;
                 ~ ^~
  /usr/include/arpa/telnet.h:50:12: note: expanded from macro 'IP'
  #define IP      244             /* interrupt process--permanently */
                  ^~~
  
  Use an unsigned char buffer instead.
