Yes:
	alias	cd	'cd `xcd $cwd \!*`'

...where `xcd' is the following shell script, located somewhere in your
PATH.  (You may have to change the `cd' in the alias to `chdir'.)

--------------------cut here--------------------
#!/bin/sh
#
# alias cd 'cd `xcd $cwd \!*`'

case $# in
1)
	echo $HOME
	exit 0
	;;
2)
	case $2 in
	/*)
		echo "$2"
		exit 0
		;;
	*..*)
		;;
	*)
		echo "$1/$2"
		exit 0
	esac
esac

# /a/b/c/symlink1/symlink2/../../src -> /a/b/c/src

SED='

	s|/[^/]*/\.\.||g
	t loop

echo "$1/$2" | sed "$SED"
