You are trying to access a variable *local* to the login shell, which is not
recommended. If you insist on doing it, make sure the cdpath setting is done
in the .cshrc, then replace the "echo..." in the popen() call with:
"csh -c 'echo $cdpath'". Note that this is *slow*. You might consider setting
an environment variable--by convention do:
setenv CDPATH "$cdpath"
then the following would work:

	char *cdpath, *getenv();
	if ((cdpath = getenv("CDPATH")) == NULL) {
		printf("Undefined\n");
		exit(1);
	}
	printf("cdpath = %s\n",cdpath);
	exit(0);
