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 &'
