#1206: "Bad interface file: System/IO.hi" in ghci when ./System/IO.hs exists

-------------------------+--------------------------------------------------
I ran into this when trying to ghci a module in the base library (from
http://darcs.haskell.org/packages/base), but it seems that ghci just gets
confused if System/IO.hs exists under the current directory. For my
purposes, it's easy enough to work around by copying the module I actually
want to work on out to another directory.

jyasskin-mac:~/Temp/bug jyasskin$ mkdir Data
jyasskin-mac:~/Temp/bug jyasskin$ mv Monoid.hs Data/
jyasskin-mac:~/Temp/bug jyasskin$ ghci Data/Monoid.hs
