[Haskell-cafe] Failure in GHC compilation

[Simon Peyton-Jones]

I've extended the "what to look for if your build fails" section in
        http://hackage.haskell.org/trac/ghc/wiki/Building/Windows

Please do keep adding to this page!  Every time you trip over something, think about whether your experience could be used to help someone else.

| Untested: setting SplitObjs=NO in build.mk might help (as there will be less
| object files to pass to ar.
|
| If ghc head is already using cabal, this problem is solved there.
