I've now tried a build strictly according to the instructions, which
is to say, I installed the binary distribution, then haskell-platform
on top of it, before building GHC from source. I get the same errors,
plus a few more (I did the quick build rather than the fully optimized
default build, so

Thanks for taking intrest in our efforts Simon :)
After three days of reading through the wiki I came up with some conclusions.

I think the main problem is that it's a very broad question. The answer
to how should I get started would be completely different for if

I've been tracking down a few (unrelated) performance bugs related to
conversions between primitive types. What these issues had in common
is that some rule failed to fire and the conversion went via Integer,
killing performance.
A related question I have is that I've some code that will map the
singleton Nats to Ints, and last time I looked into this/ had a chat on the
ghc-users list, it sounded like sometimes having Integer values constructed
in between are unavoidable. Is that still the case with post 7.6.1 ghc?

I had a discussion on the list with Iavor and others a few months back

and there were some examples and dialogue beyond that with Iavor and SPJ,
but it was
I'm trying to work around the lack of some fromIntegral/Int-Word
rules in 7.4.2. I tried something like:
int2Word :: Int - Word
#if defined(__GLASGOW_HASKELL__)
int2Word (I# i#) = W# (int2Word# i#)
#else
int2Word = fromIntegral
#endif
{-# RULES fromIntegral/Int-Word fromIntegral = int2Word #-}
I believe the testsuite now has support for inspecting assembly
output. Not sure if that would be best for your use case, but
something to consider.
