Fix bug in scavenge_mutable_list that meant mutable objects sometimes
got dropped from the mutable list.

CC_DECLARE ppr bugfix

The StablePtr dataCon is now a 'known' name

H98ified

New regression test - overlapped patterns involving labelled fields.

Added two new (read.show) regression tests for derived Read&Show instances.

simplify_pat: When simplifying a RecPat to a ConPat, expand out the missing
fields with WildPats.

-fwarn-type-defaults is your friend; misc changes to avoid H98's
'default default' of Integer to kick when what we really want is Int.

Copyright police.

Remove MUT_ARR_WORDS.  I'm not sure why we had it in the first place.

[ repeating commit, message got lost last time ]

  - Scavenge each older generation immediately after traversing its
    mutable list.

  - Make the first GC a major one: it doesn't cost much, and we get
    to garbage collection 'main' straight away.

  - Change the order of scavenging to try to minimise the size of
    the mutable lists.

Make it work.

Updates

'errors' caught by -fwarn-type-defaults

Add initial empty line to a block of errors/warnings

sigh, too hasty with dropping -monly-3-regs on Int and Word

Added oblique egcs-1.1.1 remark

don't include structs that are known to be empty within StgInfoTable and
StgHeader. Shouldn't be a problem - but egcs-1.1.1 doesn't handle them
correctly.

deriving Enum bugfixes

Track recent changes in ghc/rts so this file is still compilable.

PrelErr.hi-boot: record exports as coming from a .hi-boot file.

- don't complain if 'total memory in use' field not found in final RTS
info dump.
- add -fwarn-type-defaults to the set of -Wall warnings.

Document new -fwarn-type-defaults option.

- Decode module names before outputting the .hi file

workaround for cpp unfriendly SLIT string

a) Fix black hole bug when doing -dshow-rn-trace
   (Involved reorganising where fixity exports are dealt with
    in RnNames/RnIfaces.)

b) Arrange to apply Lint to imported unfoldings when -dcore-lint

c) Add -fwarn-type-defaults to report use of the defaulting rules for types

d) Make it so that f (error "help) --> error "help", if f is strict
   (Changes in Simplify.lhs.)

- relax the restriction that just the one open writeable handle on
  *the same file* may exist when dealing with the standard handles,
  stdout and stderr.

  Reason: the following invocation of a Haskell program,

      foo >log 2>&1

  should be acceptable.

Don't go into an infinite loop for errors generated by hPutStr when
outputing an error message.  Use writeErrString__ to output all errors
(this won't generate a Haskell exception).

Oops, import occNameUserString.

Fix a few occNameStrings that should be occNameUserString.

- include mingw32 in the list of x86 platforms supported.
- weed out ecoff debug information.

Drop uneccessary uses of lit-lits and primops

Document memoisation library.

Preliminary results of the merge of STG hugs and 990121.  These files
will compile and link, but don't work yet.

Renamed stg.h to backend.h.

Changed file organisation of STGhugs to be more like that of
MPJ's 990121 (Hugs98 beta) release, making these files redundant.

Add memo table library.

Increase PrelPack stack size.
