Update of /usr/src/master/nhc/src/prelude/PreludeIO
In directory hinken:/tmp/cvs-serv1093/src/prelude/PreludeIO

Modified Files:
	DIOError.hs IoError.hs Makefile PreludeIO.hs Show_IOError.hs 
Removed Files:
	StdIO.hs 
Log Message:
Introduce a big change in the way file-I/O is treated, permitting us to
*trace* file-I/O for the first time:
(1) Library IO now uses a ForeignObj as a Handle instead of an opaque type.
(2) Completely re-implement all file-I/O functions using foreign imports
    instead of primitives.
(3) Fix some qualified naming errors: 
        Prelude.Handle -> IO.Handle
        Prelude.stdin  -> IO.stdin  etc
