Not directly, but it isn't hard.
(1) In your .cshrc file, introduce a new variable to hold the directory stack:
	set dirs = `dirs`
(2) The commands which can change the directory stack are pushd, popd, cd.
    Introduce aliases for them which maintain the directory stack.
	alias pushd 'pushd \!* ; set dirs = `dirs`'
	alias popd  'popd  \!* ; set dirs = `dirs`'
	alias cd    'chdir \!* ; set dirs = `dirs`'
(3) Now you're away laughing.  All you have to do is write
	$dirs[3]/tcp.ip.h
