Finally!  This commits the ongoing saga of Simon's hygiene sweep

FUNCTIONALITY
~~~~~~~~~~~~~
a) The 'unused variable' warnings from the renamer work.  
b) Better error messages here and there, esp type checker
c) Fixities for Haskell 98 (maybe I'd done that before)
d) Lazy reporting of name clashes for Haskell 98 (ditto)

HYGIENE
~~~~~~~
a) type OccName has its own module.  OccNames are represented
   by a single FastString, not three as in the last round.  This
   string is held in Z-encoded form; a decoding function decodes
   for printing in user error messages.  There's a nice tight
   encoding for (,,,,,,,,,,,,,,,,,,,,,,,,,,,,,)

b) type Module is a proper ADT, in module OccName

c) type RdrName is a proper ADT, in its own module

d) type Name has a new, somwhat tidier, representation

e) much grunting in the renamer to get Provenances right.
   This makes error messages look better (no spurious qualifiers)

More missing files <sigh>

import PrelStable to get StablePtrs.

PrelForeign.StablePtr moved to PrelStable.

Add missing file.

- Add specialised closure types (CONSTR_p_n, THUNK_p_n, FUN_p_n)
- Add -T<n> RTS flag to specify the number of steps in younger generations.

Add missing file.

add missing file.

Drop unused infix decl for 'thenMaybeL' - spotted by 4.02 renamer.

More stable name additions/changes.

- Add Stable Names

- Stable pointers and stable names are now both provided by the
  "Stable" module in ghc/lib/exts.  Documentation is updated, and Foriegn
  still exports the stable pointer operations for backwards compatibility.

ifdef fix

Prepared to support i?86-*-mingw32

Added indexStablePtrArray (moved over from MutableArray)

Completeness job - added read and write ops for various sized Ints and Words.

Added --> {Int,Word}# coercion functions to export list. For internal use only

Avoid a couple of C compiler warnings.

Added osf3 guess

Tweaks to make the sources compilable again on osf3.2

Added isEmptyChan

Moved ST <--> IO coercion functions from IOExts to ST (and LazyST) docs.

- Completed lists of coercion functions provided.
- Clarified what behaviour to expect from Enum instances.

GhcReportCompiles: default is NO

more updates

Tidied up desugar warnings - will now print out patterns containing
infix constructors correctly.

Updated desugaring reg. tests

even more h98 updates, this time to codeGen tests

updates and tweaks

more h98 updates

h98 updates

Updated

Updated for H98

More Enum regression tests than you can shake a stick at.

Updated to work with current sources

Fixes to {word,int}64ToIntegerZh_fast

docfix

Added comment next to the I*_ macros to explain why having them
expand to use 'static' instead of 'extern' is a Really Bad Idea.

integerToInt64Zh: didn't handle negative integers particularly well

Bunch of bug fixes related to Enum instances. Code clean-up.

Move ST <--> IO coercion functions from IOExts to (Lazy)?ST
