Make this work with GHC 5.04.x, by slurping in rawSystem from the libraries.

Move the definition of rawSystem into a separate file which we
#include in the places it is needed.  This is slightly better than
copying the code, since we now need it in three places
(ghc/utils/runghc is the 3rd).

The commit allows to build GHCi libraries in Windows Command Prompt

Rearrange the -F/-pgmF documentation a bit.

----------------------------------------
     1. Make primOpIsCheap do something sensible
     2. Make the state hack work better
     ----------------------------------------

1.  In March 2001, we changed primOpIsCheap to
	primOpIsCheap op = False
thereby making *no* primops seem cheap.  But this killed eta
expansion on case (x ==# y) of True -> \s -> ...
which is bad.  In particular a loop like
  doLoop n = loop 0
    where
      loop i | i == n    = return ()
             | otherwise = bar i >> loop (i+1)
allocated a closure every time round because it didn't eta expand.

The problem that made us set primOpIsCheap to False was
		let x = a +# b *# c in x +# x
where we don't want to inline x. But primopIsCheap doesn't control
that (it's exprIsDupable that does) so the problem doesn't occur
even if primOpIsCheap sometimes says 'True'.  I think that perhaps
something changed since March 2001.


2.  Consider this
	case x of
	  True  -> \(s:RealWorld) -> e
	  False -> foo
where foo has arity 1.  If we are using the "state hack" we want to
eta expand here.  This commit fixes arityType in the Var case (for foo)
to take account of foo's type.

Also add -fno-state-hack to the static flags, to allow the state hack to
be switched off.

Do a much better job of slurping RULES.  

Now that stuff is slurped in lazily, as the simplifier pokes on it,
we may not get the rules as early as we might wish.  In the current
HEAD, no new rules are slurped in after the beginning of SimplCore,
and that means we permanently miss many rules.

This commit arranges that every time round the simplifier loop we
slurp in any new rules, and put them into the in-scope set, where the
simplifier can find them.

It's still possible that a rule might be slurped in a little later than
in earlier versions of GHC, leading to more simplifier iterations,
but let's see if that turns out to be a problem in practice.

In Template Haskell suppport
	dyn "M.x"
to mean "look up the qualified name M.x in the environment", which is
what you'd expect.  George Russel wanted this.

Elaborate IfaceSyn.HsWorker to give the full IfaceExtName of the worker,
rather than just the internal OccName.  Very occasionally, the worker for
a function in module A turns out to be (by simplification) a function
defined in module B.  So we must remember the module. This shows up in
package ObjectIO,
	Graphics.UI.ObjectIO.OS.Window.osValidateWindowRect
which has a worker
	Graphics.UI.ObjectIO.OS.WindowCCall_12.$wwinValidateRect

Add amd64-unknown-openbsd to the list of supported platforms.

i386-unknown-netbsd no longer refers to PCs running OpenBSD.
They are binary incompatible these days.

amd64 => x86_64
"x86_64" is what GHC has been calling this arch.

merge rev. 1.173.2.21:

Fix bug in deleteAllThreads() - shouldn't throw away the contents of
the run queue, we still need to deal with those ThreadKilled threads.

Fixed a long-standing buglet in the signatures of hs_free_stable_ptr
and hs_free_fun_ptr, both had a superfluous "*". Now everything
conforms to the FFI addendum.

Synched with versions from autoconf 2.59

A complete rewrite of ar-related tests:
* Modularized the tests
* Fixed (i.e. introduced :-) caching
* Made the test for support of "-input" more robust

Buglet in desugaring TH syntax

Document -fcontext-stack as static

The "rebindable-syntax" stuff wasn't dealing with the new location
information correctly.  This commit fixes the problem, and thereby
makes mdofail004 work right.  Maybe others too.

Revert to previous kind-check of for-alls, to avoid error message worsening
