misc ansification and -Wall cleanup

Add Marc Van Dongen's Integer improvements.  Specifically:

	- new primops: gcdInt#, gcdIntegerInt#, divExact#,
	  quotInteger#, remInteger#.

	- new definitions of quot and rem for Integer in
	  PrelNum (using the new quotInteger# and remInteger#
	  primops instead of quotRemInteger#).  Should be
	  slightly faster than before.  div & mod aren't
	  likewise optimised (yet).

	- specialisations of gcd for Int and Integer, and
	  lcm for Integer in PrelNum.

- add test cases for my URI library
- add George Russell's tests for the TimeExts library

oops, forgot to initialize bufStart in openStdFile.

Fix bogon in rule for parser/hschooks.c

New make variable: $(WithNofibHc) which defines the Haskell compiler
used to build nofib.

Define $(GHC_INPLACE) in fptools/mk/config.mk.in.  $(WithNofibHc) is
set to $(GHC_INPLACE) by default.

Fix $(MKDEPENDHS) in ghc/lib/std/Makefile.

remove cut-n-pasteo

Now that $(GHC) refers to an installed haskell compiler, use
$(GHC_INPLACE) to refer to the ghc in the build tree.

Remove long-outdated AnalFBWW

Now that $(GHC) means an installed copy of ghc, use $(GHC_INPLACE) to
refer to the ghc in the build tree.

Add drvrun008

Automatically detect installed copies of ghc, nhc and hbc and plug
them into the Makefile variables $(GHC), $(NHC) and $(HBC)
respectively.  $(HC) is now supposed to be a generic installed haskell
compiler, which defaults to $(GHC) and can be changed via ./configure
--with-hc=<blah>.

Reorganise and tidy up a few things in config.mk.in.

Derived instances should use *source* types not *representation*
types when doing their deriving stuff.  This bug prevented

	data F = F !Int deriving (Eq)

from working when -funbox-strict-fields was on

Package local configuration scripts allow to modularise the configuration (we
start by having one for ghc):
* Modularised configuration avoids unnecessary dependencies for individual
  packages.
* Furthermore, package local configuration (such as entering version
  information into rpm .spec files) is possible.

Of course, I had to get the name wrong - this has to be mangled by configure
(eg, to set the version number).

Also added dependency on gmp-devel (see discussion on glasgow-haskell-bugs).

OK, don't say you haven't been warned: Sven "Larry W." Panne waved his
Perl-wand and changed a / / into /\s+/. This fixes the problem with
multiple spaces between {-# OPTIONS ... -#}, but still fails miserably
when quotes are used, e.g. {-# OPTIONS -#include "My Own Header.h" #-}.

rpm build specifications in CVS are a first step to building packages
automatically from CVS (I test this with ghc, but support for the other
fptools components will follow)

Increase default c-t heap from 300000 to 350000 cells for nofib/real/anna.

Add i_ALLOC_CONSTR_big (== i_ALLOC_CONSTR with a 16-bit field
denoting offset of into table).  The large constant tables in
nofib/spectral/hartel/nucleic2 need this.

Correctly detect saturated applications of tuples, following
recent change to Tuple machinery in Hugs.

Remove unused machinery for computing the amount of heap a BCO will
allocate.  This isn't used because Hugs uses the allocate() mechanism
rather than allocating by advancing Hp.

test $(IncludeTestDirsInBuild)

80-columnify

Don't create a new infotable for every constructor application.
Amazingly, that's what the codegen.c used to do.  It didn't generate
vast numbers of redundant infotables until recently, when I changed
translate.c to generate saturated constructor applications in line.
Prior to that, there was only ever one application of each constructor,
so the old scheme was ok.

Also, fix the assembler so that info table ptrs are commoned up.
Eg, for [1,2,3], store only one copy of the address of the (:) itbl,
rather than 3, in the BCO.

Fixed a FunDep leak in tcSimplifyToDicts (they weren't being filtered out),
and fixed bug in instance improvement (matching wasn't being done correctly
for polymorphic instances).

Remove compile-time address space allocated to tuples, and remove all
references to TUPMIN.  I think I have fixed the address mapping for
when TREX is defined, but you never know.

Remove Hugs' special treatment of tuples, and instead have them as
just another Tycon.  This is to make interworking with GHC simpler.

Put tuple entries in the Tycon table.  Modify isTycon, isTuple, tupleOf,
mkTuple and whatIs so that client code doesn't see any difference.
Add allocTupleTycon to manufacture tuple Tycon entries as startup.

Only detect (# and #) as special tokens when parsing interface files.

Add missing stdout file

Some minor tidying-up that should remove an occurrence
of an empty Let Rec that confused CoreLint.dumpLoc.

Simon

Fix a major bug in exporting unfoldings involving existentials.

Change core printing so that we put an '@' before type
variables in case patterns.  This only affects existentials.

	case x of
	  C @ a x y -> ...

Here 'a' is an existentially quantified type variable, and the
'@' signifies this.  We continue to omit kinds and type on case-bound
variables; the type checker can fill them in.

The reason for this change is that type variables and term variables
live in a different name space, so we need to know which name space
is  involved when binding one.  How this ever worked I will never know.


While I was at it, I also arranged that -ddump-rn prints out whatever
it has even if it finds errors.  Adding -dppr-debug prints even the
unfoldings on imported things.

Simon

Change printDump so that it prints in user style by default.
This means that (eg) -ddump-simpl output is much more readable...
but you may get confused by variables that look the same but aren't.

To recover the previous behaviour use -dppr-debug

This change only affects compiler hackers; let me know if it
has any good or bad effects.

Simon

Install an interface file for PrelGHC, too.

fixIO versionitis

Replaced $(H_FILES) $(H_CONFIG) with $(wildcard *.h), it seemed to be
a cut-n-paste bug from another Makefile where they are defined.

Extend getTyVarsToGen to take the closure of the set of tyvars
with respect to functional dependencies.  Really simple programs
using functional dependencies work now.  Also fixed a small glitch
where trivial (empty) FunDeps were being tossed into the context willy nilly.

Remove some hooks into the Prelude which Hugs no longer needs to know about.
