dsExpr: make sure special case for unboxed tuple patterns only
'fire' when the tup. pat. is unboxed.

Removed unused args from Id.mkIdVisible and Name.mkNameVisible.
Perpetuated Name.mkTopName hack in Name.mkNameVisible.

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.

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.

Dead code removal

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.

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

CmdLineOpts needs -K3m for some reason.

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.

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.)

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

long long support: cleared up Real vs. virtual regs. confusion (I hope!)

A 'foreign export dynamic' *does* bind a Haskell name.

Be a little bit more user-friendly when encountering record puns,
which is no longer supported by Haskell. Instead of a Plain Old Parse
Error, print out

  foo.hs:11:11: Haskell 98 does not support 'punning' on records ....

Hopefully that should give the user a big enough hint at what's
going wrong..

Tweaked to accept empty declarations (again.)

Haskell 98 updates.

Remove punning.

#if __HASKELL1__ > 4
import Ratio (numerator, denominator)
#endif

Remove Void use.

Parser didn't like "instance Foo X where {}". Does now.

wibble

fix isAlphanum/isAlphaNum problems.

A couple of Int type signatures to avoid H98 Integer defaulting.

Removed debugging code that accidentally was left behind.

Fixes to support .hi unfoldings containing "_ccall_ dynamic"s

Assorted minor Haskell 98 changes:

  * Maximal munch rule for "--" comments
  * _ as lower-case letter, "_" is a reserved id. Prefixing unused
    variable names in patterns with '_' causes the renamer not to
    report such names as being unused.
  * allow empty decls
  * comprehensions are now list comprehensions, not monadic.
  * use Monad.fail to signal pattern matching errors within
    do expressions.
  * remove record punning.
  * empty contexts are now legal  (go wild!)
  * allow records with no fields
  * allow newtypes with a labelled field
  * default default is now (Integer, Double)
  * turn off defaulting mechanism for args & res to a _ccall_.
  * allow LHSs of the form  (a -.- b) x = ...
  * Main.main can now have type (IO a)
  * nuked Void (and its use in the compiler sources.)
  * deriving machinery for Enum now also generate 'succ' and 'pred'
    method bindings.

Arrange for Makefile dependencies to be generated on misc
parser/ helper code.

Added indexFS,

   indexFS :: FastString -> Int -> Char

Z-encodings for '/' and '.' were both 'Zd'.  Change '.' to 'Zs'.

Generate static closures with float/double fields properly.

Fix endianness problems in info table generation.

Add missing export of warnPprTrace (for WARN macro).

Fix RnEnv.mkPrintUnqualFn

Add missing pattern to tidyNote.

Small changes to make the compiler boot itself

Add debug macro WARN
