M-<char> can be different from ESC <char> even in current emacs.
I use the following command:
       (setq meta-prefix-char nil)         ;; no meta char (ESC is escape)
and here are the key description for M-c and ESC c :
  M-c runs the command Alt-C
     which is an alias for `compute' in `FK'.
  ESC c runs the command capitalize-word
