tcsh (and csh, for that matter) is known for it's lack of
file-descriptor manipulation in the prompt.  You can do limited stuff like:

    % ./program >& program.stderr.log &

which will redirect only stderr of ./program in program.stderr.log, but
I don't know of a way to redirect file descriptor 2 to where 1 points at
that point.

I tend to use too many times the following trick:

    % /bin/sh -c './program 2>&1 > error.log &'

Ciao,
