More hs-boot file troubles

Not only that, but your boot file contained instance declarations! That's a pretty new feature, and it didn't work right. Should be ok now.

|
| Looks like there's still something wrong with iface checking and
| .hs-boot files, in today's head (since the latest SPJ patches).
|
| Duncan and I are working on a fork of base using stream fusion for the List
| library. We needed a new .hs-boot breaker between Data.List.Stream and
| GHC.Num. While this was enough to get it compiling last week, now, after
| getting past the boot file, and Data.Stream, GHC.Num itself fails with:
|
| ../../compiler/ghc-inplace -H16m -O -fglasgow-exts -ddump-simpl-stats -cpp -Iinclude -"#include"
| HsBase.h -funbox-strict-fields -package-name base-2.0 -O -Rghc-timing -fgenerics -fgenerics -split-
| objs -c GHC/Num.lhs -o GHC/Num.o -ohi GHC/Num.hi

| Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
|
| <<ghc: 110807872 bytes, 16 GCs, 4029053/7271872 avg/max bytes residency (3 samples), 18M in use, 0.00
| INIT (0.00 elapsed), 0.63 MUT (0.71 elapsed), 0.28 GC (0.29 elapsed) :ghc>>
| make: *** [GHC/Num.o] Error 1
|
| To reproduce this, grab a ghc tree, without libraries/base, and instead take base from:
|
| $ mkdir build
| $ cd build
| $ lndir -silent ../ghc
| $ cd libraries
| $ darcs get http://www.cse.unsw.edu.au/~dons/code/streams/base/
| $ cd ..
| $ autoreconf
| $ ./configure
| $ make
|
| And it should fall over building base.
|
| As it is, this bug is rather painful, since we can't build base with our stuff.
| Should we be considering splitting up Data.Stream/Data.List.Stream
| (http://www.cse.unsw.edu.au/~dons/code/streams/list/) to avoid adding Num.hs-boot?
|
| This would mean break up the code to instead map onto the existing
| GHC.List/Data.List split, and somehow breaking up Data.Stream as well.
