With Haskell98, Enum.enumFromThen can generate sequences that
are either increasing, decreasing or infinite.

Resurrect ticky-ticky profiling.  Not quite polished yet, but it
compiles and produces some reasonable-looking stats.

Add $(HC_OPTS) to $(CC_OPTS) - this is necessary to get the per-way
flags into the plain-C compilations.

Make use of -F<factor> flag in the two-space collector.

The BLACKHOLEs created when entering a CAF for the first time are now
CAF_BLACKHOLES, distinguishing them from the blackholes created by
lazy blackholing.

This enables the lazy blackholing algorithm to be optimised by not
blackholing a section of stack that has already been traversed.

Increase CmdLineOpts stack size to 4M.

hook in GetOpt docs

Back again - somehow got lost.

Dead code removal

Increase PrelNum stack size to 3M.  Funny, it only needed 2M yesterday.

Don't forget to reset the evacuated flag on to-space blocks when
generations == 1.

Support '+RTS -G1'  i.e. a two-space collector.

Small fix to slop skipping.

Change the sizing for intermediate generations.  Now the formula is

	max_size = max (oldgen_max * g / generations,
			RtsFlags.GcFlags.minOldGenSize)

Types of foreign imports weren't being zonked, with the lethal conseq.
that any unbound kind variables weren't being defaulted to something
sensible.

Showed up when trying to compile a 'foreign import' with type

  StablePtr a -> IO ()

Banner message now advertises Haskell 98.

- Add -F<factor> flag which governs the threshold size of the oldest
  generation.

- Add RtsFlags.GcFlags.minOldGenSize (no flag yet) so that we don't
  have to guess the initial size of the oldest generation.

foreign decls: use wlkHsSigType, not wlkHsType, since the tysig may
have implicitly quantified tyvars.

Increase stack size for PrelNum.lhs.

CmdLineOpts needs -K3m for some reason.

4.02 updates.

Update for 4.02.

Update for 4.02.

The Fight against needless use of (++) continues.

mkExportAvails: remove NotAvailable entries corresponding
to 'hidden' entities from 'unqual_avails'. Not needed and
leaving them in causes bother later on in the renamer.

This fixes the problem of compiling

   module B ( module A ) where { import A hiding ( a ) }

Regression test added to check for this - will commit soon.

bracket and bracket_ had a less general type than they should
have. They now match what the docs says.

Added showBin (binary nums - no, the 'old' showBin & friends hasn't been resurrected)
+ showIntAtBase to export list:

   showBin       :: (Integral a) => a -> ShowS
   showIntAtBase :: Integral a
	         => a            -- base
	         -> (a -> Char)  -- digit to char
	         -> a            -- number to show.
	         -> ShowS

Misc doc-fixes and updates.

Remove debugging code from freeStablePtr.

constructNewHiFile: regular expressions which substituted new
module filename for old in hifile_target, didn't quite work.

Print out warnings/errors in the order they occur in the source code.
(Well...almost, warnings are sorted and printed out on a per-pass basis.)

Update for new stats output.

Only reset oldest_gen->max_blocks on a major GC.

Update

Completed support for GAMMA_VAR.

- BLACKHOLE_BQ is a mutable object, because new threads get added to
  its blocking_queue field.  Hence add a mut_link field and treat it
  as mutable in the garbage collector.

- Change StgBlackHole to StgBlockingQueue while I'm at it.

- Optimise evacuation of black holes: don't copy the padding
  words, just skip over them.

- Several garbage collection fixes.

- Improve sanity checking: now the older generations are fully checked
  at each GC.

- do MVARs properly.

- skip over slop between objects, by searching for the first info pointer.
  this works for slop created by updates, for example.

Added protos for freeHaskellFunctionPtr() and createAdjustor()
(suggestions as to what might be a more appropriate home for these
are welcome.)

Added debugging code to freeStablePtr macro

Fixed a couple of bad bugs in the implementation of 'foreign export ccall dynamic'.
