Mention that GHC is required for building GHC.

Point directly to the Building Guide from here.

Better documentation for unboxed types; merge to STABLE

Wibble to message

------------------------------------------------------
	Report top-level implicit parameter errors more nicely
	------------------------------------------------------

Consider
    module Main where

	main = let ?x = 5 in print foo

	foo = woggle 3

	woggle :: (?x :: Int) => Int -> Int
	woggle y = ?x + y

GHC's current rules say that 'foo' is monomorphic, so we get
	foo :: Int
but we also get an unbound top-level constraint (?x::Int).  GHC 6.2 emits a
message like:
     Unbound implicit parameter (?x::Int)
     arising from use of `woggle' at ...

The point is that THERE IS NO WAY FOR THIS CONSTRAINT TO GET BOUND,
because we don't have a top-level binding form for implicit parameters.
So it's stupid for 'foo' to be monomorphic.

This commit improves matters by giving a much nicer error message:

     Implicit parameters escape from the monomorphic top-level binding(s) of `foo':
       ?x::Int arising from use of `woggle' at tcfail130.hs:10:6-11
     Probably fix: add type signatures for the top-level binding(s)
     When generalising the type(s) for `foo'

Respect --exclude-module in ghc -M; some tidying up as well

Comments and type sig

The HEAD is now 6.5

In the fragments of Haskell code which setup buffering and flushing
for the std Handles in GHCi, qualify names with System.IO rather than IO.

Need to add -I. when compiling with GHC 6.3+

Fix another substitution-related bug in CoreLint

Move the in_haskell check to somewhere that works for the threaded RTS too.

add a prototype

Make setProgArgv() set the RTS's idea of the prog name too.

Document dependency printing

Dump package config only with -v4
Dump module dependencies (ghc -M) with -v2

Tidy output

Make sure that the argument of DataToTag is evaluated; rather a horrible piece of code, I fear

Import trimming

Add a helpful sanity check: if we try to re-enter the scheduler from
Haskell code without going via suspendThread()/resumeThread(), such as
when you have a 'foreign import unsafe' that should be 'safe', then you
get an error message.

include ghcplatform.h

Fix sed command line

Futher gruesome makefile hackery to deal with building lib/compat

Fix two separate bugs in CoreLint, both relating to the fact that the substitution
it carries must be applied exactly once.

This cures a lint crash in Text.ParserCombinators.Parsec.Perm, which was triggered
by -O2; specifically, SpecConstr generated some terms with heavy shadowing of type
variables.

Fix isLinkMode and adjust formatting a little

Add an entry for "duplicate definition for __module_registered"

Finish docs for hs-boot files; please review!

First cut at hs-boot documentation

Generate some sensible code when presented with the output from gcc -O2

whitespace

hack upon the hack: confine the hack to -fasm, because gcc is too
stupid to optimise away the extra temporary.

small perf hack in emitVectoredReturnInstr: work around lack of CSE in
the NCG by assigning info_amode to a new temporary.

Add __attribute__((used)) to static functions, as gcc 3.4 -O2 is in the
habit of throwing them away.

Fix the source_unchanged test in the Hsc phase

--------------------
	Command-flag cleanup
	--------------------

* Fewer cases in GhcMode: eliminate DoMkDLL, DoLink, both in favour of
  StopBefore StopLn

* Replace the NoLink boolean with a GhcLink three-way flag:
	NoLink, StaticLink, MakeDLL

* Corresponding plumbing to link it all up.

more regex test down to libraries/base

Tidy up stop-phase passing; fix bug in -o handling for ghc -E X.hs -o X.pp

---------------------------
	Some Template Haskell fixes
	---------------------------

* Tidy up conversion from TH.Name to RdrName.RdrName. It was partly
  duplicated between Convert.thRdrName and TcSplice.lookupThName.
  Now it's all in one place: Convert.thRdrName

* Fix a bug in TH.tupleTypeName/TH.tupleDataName (GHC.Tuple -> Data.Tuple)

* Export appEs from Language.Haskell.TH
