>To my knowledge, /etc/cshrc is sourced by all occurences of csh.

Your knowledge is incomplete.  It turns out he's running SunOS, and the
SunOS "csh" doesn't source "/etc/cshrc"; neither does the 4.3BSD "csh"
from which it's derived.  Some versions of "csh" may have such a file -
or an "/etc/login"-like file, sourced only by login shells - but with a
different name.
