I think it's there bacause of a linking problem. SWAT needs to link to
some code that uses Files[] but Files[] is declared as part of a
module that SWAT can't link to, so SWAT needs to declare its own copy
to link correctly.

Sorry for the vague description, I'm going from a hazy memory and
neglected to comment the declaration (phooey).
