This came from v.in.dxf and should work. (note reference to
mask.dxf. The US Army .. came from the v.in.dxf program.)

I have enclosed the original file so that
tabs, spaces, cr with no lf, whatever, is preserved.

This exact file worked in pre3 on my Sun machine.
Let me know if it does not work for you.

(Also note that East/West is negative, North/South 
is positive for me.  You might check this.)
