The default code produced by the Delete key and interpretation by X is fine.
Xterm produces the standard ANSI sequence "^[[3~" as it should and this is 
encoded in termcap for xterm as delete character. And this will work as 
expected for many applications working within an xterm window. The problem 
comes about that the shell does not honour this termcap entry.

Don't fool with xmodmap; it will work against you in applications -- just 
bind the key sequence in your shell (tcsh?)
$  bindkey "^[[3~" delete-char

I guess it would not be too difficult to extract the correct string from
termcap so that it worked for all (most) terminals but most now use the 
standard ANSI sequences so it is probably not worth the effort.
