You could create a file and see if "find . -name THAT-FILE" finds it
and prints its name like a Unixy `find' should, for example.

You are looking at the docs for the wrong variable: your code, quite
correctly, works with system-type, not with window-system.
windows-nt and ms-dos are values of system-type, while the
corresponding values for window-system are pc and w32 (assuming these
ports are not run with the -nw switch).
