- change prototype of async proc calls to

      typedef int (*DoProcProc)(void *param);

  i.e., have the proc return a result. Turned out that almost all
  uses of the primop ended up encoding a result via their 'param'.

- when adding new I/O requests, shorten the time the IOManager
  lock is held. Helps to keep down the size of the thread pool.

ppFilesFromSummaries.toPpFile: make it clear that file paths are being eq-tested here

Put a newline after showing an I/O error.

Respect -odir in one-shot compilations.

Arrow notation: add a new (more primitive) form of command:

	cmd ::= ... | cmd aexp

analogous to ordinary application, and also represented using HsApp.
To avoid an overlap, the syntax for combining forms is changed to

	(|aexp cmd1 ... cmdn|)

Add extra functions operating on outsized tuples (used by the translation
of arrow notation).

interruptible(): add missing BlockedOnDoProc case

awaitRequests(): BlockedOnDelay threads not expected on blocked_queue

unblockThread: barf() string wibble

[win32]delay#: set why_blocked to BlockedOnDoProc since we're appending the thread to blocked_queue

Fix the big-char-literal parsing issue in External Core, correctly this time

Give a more sensible type to big character literals in ExtCore (but it still looks odd to me)

External Core was ignore sign on rational

Markup fix

Part of the fix to External-Core (:Main, not $Main), which got left out

Remove redundant Var.hi-boot

---------------------------------------
	Wibble to GHCi constraint simplification
	---------------------------------------

The new GHCi constraint-simplification story, with defaulting for
Show, Eq, Ord, should only apply to command-line expressions, not
to modules loaded by GHCi.

Hence new variant, TcSimplify.tcSimplifyInteractive

--------------------------
	Fix two External-Core bugs
	--------------------------

1.  An inadvertent "let x = ...x..." bug in TcRnDriver

2.  Adjust the new -main-is story, so that the root module is called
	":Main" instead of "$Main".
    This means that the z-encoded module name is "ZCMain" rather than "zdMain",
    which in keeps the External-Core lexer happy.  And is more consistent generally.

3.  Make the renamer happy to see definitions from modules other than the "home" one,
    when doing External Core.  In the main module, there'll be a definition for
    ZCMain.main.

	Type defaulting in GHCi
	-----------------------

	[Merge to stable branch, I think.]

[Part 2 to this commit: add Eq and Ord, to allow

	[] == []

at the prompt.


      Extend type defaulting in GHCi so that

	ghci>  []
	[]

      works.  Suggested by Ralf Hinze.

New primop (mingw only),

  asyncDoProc# :: Addr# -> Addr# -> State# RealWorld-> (# State# RealWorld, Int#, Int# #)

which lets a Haskell thread hand off a pointer to external code (1st arg) for
asynchronous execution by the RTS worker thread pool. Second arg is data passed
in to the asynchronous routine. The routine is _not_ permitted to re-enter
the RTS as part of its execution.

Trim more imports

Dont report assert as unused; merge to stable

Some random import trimming

autoconf probably knows best about vfork()

Fixes two minor bugs that I came across in the old
CgCase code generation:

1. We were generating
	tmp = Sp[1]
	... more uses of Sp[1]....
instead of
	tmp = Sp[1]
	... more uses of tmp....
in the (case v of ...prim alts...) situation

2. The cost-centre restoration wasn't right for let-no-escapes

I kept this fix separate, becuase it does change the code generated
slightly.

------------------------
       Tidy up the code generator
	------------------------

The code generation for 'case' expressions had grown
huge and gnarly.  This commit removes about 120 lines of
code, and makes it a lot easier to read too. I think the code
generated is identical.

Part of this was to simplify the StgCase data type, so
that it is more like the Core case: there is a simple list
of alternatives, and the DEFAULT (if present) must be the
first.  This tidies and simplifies other Stg passes.

Mention unix package only for non-WinDoze builds.

The starting page of the GHC Documentation contains no autoconf tricks
anymore, so keep things simple...

Tweaked help strings for --enable-objectio and --enable-hopengl options.

Wibble to printing HsSyn variables

Add ancient HEP document, which might be revived.

Back out previous revision, we'll tackle this a different way.

Another buglet in TcRnDriver for ghci

-------------------
	Fix a subtle GC bug
	-------------------

In GHC 6.0, the top-level definition

	f = g

gets compiled as a *non-updatable* THUNK_STATIC closure.  Being non-updatable,
it gets only 1 payload field.  Alas, the static-link field for a THUNK_STATIC
goes in the 3rd payload field.  Disaster.

Solution: make such things updatable. This is probably good because it turns
f into an IND_STATIC, which gets shorted out.  (Even better would be to allocate
an IND_STATIC in the first place.)
