Re: C Mode Comments

I am running GNU Emacs 20.2.3.  M-; does not run comment-dwim, but runs 
indent-for-comment.

What I am looking for is a command that would have the effect of killing 
an entire comment.  For example, given:

int x;      /* this is a comment */

Only "int x;" would remain on this line of code.

Thanks.
