[cvs-nhc98] Single-file versions of the IO and Ratio libraries. These

malcolm: Fri Nov 23 13:27:49 CET 2001 Update of /usr/src/master/nhc/src/prelude/Hat In directory hinken:/tmp/cvs-serv11285 Added Files: IO.hs IOPrimitives.hs Ratio.hs Log Message: Single-file versions of the IO and Ratio libraries. These are not yet compilable. The IO library relies on many compiler-specific primitives (see IOPrimitives), which need to be wrapped by hand. The Ratio library cannot be compiled directly by nhc98, because its definitions clash with those in the real Prelude/Ratio modules. However, I think it can be _transformed_ by the portable src->src tracing transformation.
