When starting tcsh 6.12 as root, it does not source /etc/csh.login. Even though the tcsh man page does not seem to mention this behaviour, it's apparently standard (Suse 7.3's tcsh behaves the same). Gentoo's tcsh scripts rely on csh.login to set the PROMPT variable, which doesn't work for root.
tcsh seems to load /etc/csh.login for me. I confirmed this by adding a echo foobar to it. Are you staring tcsh with the '-l' flag?
I looked a bit more at this problem, and tcsh seems to be behaving correctly -- it only sources csh.login when it's a login shell. When opening up a KDE Terminal, for example, it's not a login shell, and csh.login is (correctly) not sources. This however means that the aliases and the prompt aresn't set to anything sensible when using a KDE Terminal shell. These should be set in csh.cshrc, and csh.login should only contain things that are relevant only to login shells. Ideally tcsh should come with csh.login and csh.cshrc files that have some intelligence in them, similar to the ones found with the SuSE tcsh. Seems like most of the stuff in those are based on open source config files that were published with tcsh in the past. So maybe time to start a gentoo set.

Ill have to agree that our tcsh support is not what it should be. I however do not use it, so would not want to mess with it. If you can get a sane setup working that some dev that uses tcsh can verify, feel free to open a new bug.
