Compile lndir for Cygwin even under mingwin, because mingwin doesn't have
symlinks (or sys/param.h).

lookupClosure not used.

make ghci-inplace work

Update the interactive context in cmRunStmt rather than hscMain.

Unload temporary bindings from the ClosureEnv properly at cmLoadModule time.

fix dumping in desugarExpr

- message wibbles

- in one-shot mode, make sure the interface file follows the module rather
  than the filename of the source.

ILX back-end. WARNING: this is code copied in that was previously added to
4.06. It's not remotely sane to try to compile it at the moment; that's what
I've got to do next. Don't worry, it's all #ifdefed at the moment.

Move seq/par munging from CoreToStg to CoreSat

Move findDefault, findAlt from SimplUtils to CoreUtils

Dont print generic insts if there arent any

Make it build without GHCI

Implement do-style bindings on the GHCi command line.

The syntax for a command-line is exactly that of a do statement, with
the following meanings:

  - `pat <- expr'
    performs expr, and binds each of the variables in pat.

  - `let pat = expr; ...'
    binds each of the variables in pat, doesn't do any evaluation

  - `expr'
    behaves as `it <- expr' if expr is IO-typed, or `let it = expr'
    followed by `print it' otherwise.

Make foldl more efficient; see comments with foldl

Fix a core-lint problem with -hi-boot files

- Move compareInt# to PrelBase (where it was duplicated)
- remove some unnecessary truncations in the Int8/Int16 code

print GHC's version in the panic message

Fix a problem with duplicate instances appearing in the interpreter
after reloading modules.

merge rev. 1.49.2.1 from ghc-4-07-branch

don't need to derive Show on the Package datatype now.

Added description for -fno-method-sharing.

Shouldn't that flag be under the heading `Individual optimisations'?

Add --keep option to not delete *.hs_make.c.
Add -c -l -C -L -i as synonyms for --cc --ld --cflag --lflag --include.

Add -mno-cygwin to CPP rather than CPPFLAGS, so that it gets into mkdependC
and the like.

Since fromInt was degraded to a function, do the same with toInt.

Add -mno-cygwin to CC_OPTS on mingwin (we were building all our auxiliary
programs Cygwinised before...).

-hisuf is now done by fptools/mk/target.mk

fromInt

Remove fromInt from class Num, though it is retained
as an overloaded operation (with unchanged type) in PrelNum.

There are quite a few consequential changes in the Prelude.
I hope I got them all correct!

Also fix a bug that meant Integer (and its instances)
wasn't getting slurped in by the renamer, even though it
was needed for defaulting.

Add more tests

Move rules to tag .hi files with the way from hslibs/mk/target.mk to
fptools/mk/target.mk.

Tidied up and removed discussion of solved mingw package problem.

Add integerTyCon to the ubiquitous types

Make this work with GHC 4.08, and remove duplicate (old) copy of Andy
Gill's HTML combinator package.

Improve the identity-case transform in strange Coerce situations

More wibbles

-O turns on -fignore-asserts.

Be a bit more careful in CoreSat.deLam

Apply tweaks needed to let this compile: remove syn_map argument from
typecheckExpr in HscMain, import PrelNum.fromInt to modules which
use integer literals with -fno-implicit-prelude flag.

It crashes later, on Directory.hs:
ghc: panic! (the `impossible' happened):
        srtExpr

I'm not sure if resolving numeric literals to top-level definitions
of fromInt/fromInteger with -fno-implicit-prelude is a good idea.
Using names from whatever module is called Prelude would be IMHO
better, probably when -fglasgow-exts is given. Prel* modules themselves
would import PrelNum as Prelude.

Both schemes break for fromInt, which is non-standard and by default
it's visible neither at the top level nor in the Prelude module. My
proposal for dealing with it is as follows (assuming that fromInteger
is taken from the module locally called Prelude instead of the top
level): when the standard Prelude is used, take fromInt from PrelNum;
when a Prelude replacement is used, use fromInt from it if available,
otherwise use its fromInteger instead. That way Prelude replacements
can ignore this non-standard extension and get the expected behavior,
or they can also choose to use this extension (in a way compatible
with Haskell implementations which allow to replace Prelude but don't
have fromInt).

More doc hacking.

Call for Release Notes (CFRN): the 5-00-notes.sgml file is currently a
skeleton only; PLEASE add or expand entries for things you've done.

Eta expansion wibbles
~~~~~~~~~~~~~~~~~~~~~
* Don't eta reduce, and do eta expand,
  data con workers and primops

  Reason: they don't have bindings, so they aren't really
  ordinary variables.

This is a bit of a swamp, provoked by moving CoreSat later,
something I'm beginning to wonder about...

Not are things settled yet -- I think some rules may
not fire that should because of constructor worker/wrapper
issues.  E.g when you have   foldr (:) [] xs = xs

Import wibble
