The solution I use is to use xrlogin instead of rlogin, and run
xrlogind on the remote machine.

xrlogin and xrlogind are programs I wrote.  xrlogin packages $TERM and
$DISPLAY up into a string, stuffs it into $TERM, and execs rlogin.
xrlogind recognizes a TERM variable of the special format produced by
xrlogin and unpacks it into setenv commands (I use a csh-based shell).

Thus, my .cshrc everywhere contains

	eval `xrlogind`

and if I use xrlogin to log in remotely everything works.

(I am describing the technique rather than offering code because the
code depends on local include files and library routines to such an
extent that I don't feel up to getting it in releasable shape.  If you
want the code anyway, drop me a line.)
