some backwards-compatibility updates that should have gone into 2.09.

export freeze/thaw array operations.

Remove wired-in runST, instead provide a type signature using the
universal quanitification extension.

Also move runST from STBase.lhs into Unsafe.lhs so that it won't get
inlined anywhere.

fix huge bug in extractHsTyVars - the list returned wasn't always a
set (i.e. it could have duplicates).  This screwed up support for
universal quantification in a couple of places.

New matchExport, changed types for match, matchSimplify, changes related with MatchResult, EquationInfo and a lot or more changes

Deleted old Shadow stuff

Changes related with new types of MatchResult, EquationInfo and matchSimplify

Deleted DsWarnFlavour

Deleted old Warning staff and added new ones

Changes related with the new type of MatchSimply

change match by matchExport and changes related with the new type of MAtchResult

Added matchExport to export list and changes matchSimply and match types

Added matchExport to Match export list

data types with one constructor doesn't need WildCadr cases

Added -fwarn-simple-patterns option

Deleted NAmedThing Constraint of Outputable InPat

HsLit instance of Eq; need by Check

New module; proper lint for patterns

Added Ord instance to ThreadId; added note saying that thread identifiers are currently not implemented; renamed readChanContents to getChanContents

Added stuff on interface filenames being dependent on module names; documented -fwarn-duplicate-exports

Document new mkdependHS options

Append -lnsl when using -syslib ghc on Solaris2 boxes (BSD nwork support.); -w as synonym for -Wnot; pass -fsignatures-required through to compiler proper.

doc fix

-fwarn-duplicate-exports: only warn about explicit duplicates

Renamed {read,write}Sample to {read,write}SampleVar

prune #* and .#* when making source dist.

add a few @'s.

sigh, fix a couple of dodgy references.

fix bogon in last commit.

add pointer to the release notes for 2.09.

fix for booting with 2.01 <= GHC < 2.09

Does not belong in source tree.

Move StableLoc (and assoc. access functions) from CgBindery to CgMonad. Done to avoid having to give the home of Maybe in CgBindery.hi-boot.

wibble

Added mapMaybeRn

Check for duplicates in exports lists when -fwarn-duplicate-exports is on

Added -fwarn-duplicate-exports option

Update information on Glasgow extensions and the associated libraries.
Pull in Alastair Reid's library document as a temporary measure: this
will be replaced by a link to the SGML version in the future.

literatize and add a few forgotten things.

add ST macros for GHC < 2.00.
