I've just spent over 2 hours trying to solve this for a tcsh script and my solution turned out to be pretty simple...

set X = `echo $* | awk -F " " '{print $NF}'`
somecommand "$X"

I'm quite sure this would be a portable solution, but I'm not that experienced with scripting yet...

Hope it helps someone anyway,

Vince

For tcsh:

set X = `echo $* | awk -F " " '{print $NF}'`
somecommand "$X"

I'm quite sure this would be a portable solution, except for the assignment.
