Already fixed in CVS.

Hmm, probably the newer version of gcc on Cygwin provides these
definitions but the older one didn't.

Is it possible that you have done a 'make clean' at any point?
It would remove all the prelude .hc files, and the only solution is to
unpack the tar distribution again (and re-apply any fixes).  But in any
case, the files CIx.* should be found in the directory src/prelude/Ix,
not src/prelude/IO, so something odd is going on which I can't explain.
