This patch tides up Ian's fix a little. In particular, if if you
{-# SOURCE #-} import a module from a different package, you now 
get a much more civlised error message.

Suppose we import anotherPackage:M, which exports things from
anotherPackage:Internal. Then GHC will want to read
anotherPackage:Internal.hi.

However, if we have also SOURCE-imported thisPackage:Internal then
we don't want GHC to try to read anotherPackage:Internal.hi-boot
instead.

The mapping that tells us whether a module is SOURCE-imported uses just
the module name for the key, so we have to check the package ID before
looking it up.

Fixes #3007.

Type synonyms that don't mention one of their type parameters on the 
RHS are a pain in the neck.  This patch fixes a long-standing bug (that
simply has not appeared before) in that exprType could return a type
mentioning an existentially-quantified variable (in one of those ignored
argument positions).

See CoreUtils Note [Existential variables and silly type synonyms]

The fix is not entirely beautiful, but it works, and is very localised.

This checks that hackage would accept the packages.
Currently warnings are printed, but don't result in failure.

The Convert stuff should not panic if the programmer hands over an
invalid TH term; instead it should give a graceful error message.
Largely this had been done, but not for do-blocks, so this patch
fixes that problem.

Moreover, I did some refactoring and tidying up, which is why
so many lines of code have changed

This is just a blatant typo, where Any1 :: *->* was getting mixed
up with Any :: *.

The previous patch simply gave up for view patterns; this version
instead treats them like n+k patterns and gives signficantly better
results.

Less code, too.

This makes GHC work even if you are actually running it in 64bit mode,
e.g. on OS X 10.6 Snow.

This is a bit kludgy. We've hit the maximum number of arguments you can
have in the for loop for adding files to the bindist list, so this just
splits the list in 2.

This patch modifies darcs-all to have feature parity with push-all by
recognizing two new options.

    * -i, equivalent to --ignore-failure in push-all
    * -r <repo>, specifies the remote repository darcs commands will use

Some example commands:

Get the libraries from a repository of your choosing. This is useful
when working with a git mirror:

    $ ./darcs-all -r http://darcs.haskell.org get

Pull changes. Used to be:

    $ ./push-all --pull http://darcs.haskell.org

Is now:

    $ ./darcs-all -r http://darcs.haskell.org pull

Or to use the default remote of the ghc repository:

    $ ./darcs-all pull

The .dyn_hi files currently depend on the .dyn_hi files of modules that
they import. But they actually want the .hi files of modules from
another package.This we make the .dyn_hi files depend on the .hi files
so we are sure that they exist and are up-to-date.

Stops make going into an infinite rebuilding loop

Also, use C99-style array initialisers

For consistency with other RTS exported symbols
