Please don't use just `C-' or just `M-' for sexp
commands.  Please use the conventional `C-M-'.

FWIW, `C-M-k' for `kill-sexp', and `C-M-<backspace>
for `backward-kill-sexp', work on at least some
platforms, such as MS Windows. 

And for uses of Meta that are problematic for some
platforms, users can always use ESC.  E.g. `ESC C-k'
instead of `C-M-k' or `ESC C-<delete>' for
`C-M-<delete>'.  Admittedly not as handy, but usable
(and users with that problem can always rebind them).

(BTW, did you mean `C-M-<delete>' instead of `C-M-DEL'?
The latter doesn't seem to be bound by default.)
