      ------------------------
             Tidy up the code generator
      	------------------------
      
      The code generation for 'case' expressions had grown
      huge and gnarly.  This commit removes about 120 lines of
      code, and makes it a lot easier to read too. I think the code
      generated is identical.
      
      Part of this was to simplify the StgCase data type, so
      that it is more like the Core case: there is a simple list
      of alternatives, and the DEFAULT (if present) must be the
      first.  This tidies and simplifies other Stg passes.

      Push down CPPFLAGS, CFLAGS and LDFLAGS.
      
      Now ./configure should pick up those flags and hopefully make life a bit
      easier for packagers. Notice that some flags which work fine for 'ld'
      won't work with ghc, e.g. the combination "-Wl,-E" which 'gtk-config --libs'
      suggests, so you'll usually want to set only -I or -L.
      
      > ghc -Wl,-E
      ghc-6.0: unrecognised flags: -Wl,-E

      From genargs.pl:
      # This program generates a partial Haskell list of Strings from
      # words passed via stdin suitable for use in package.conf, e.g.:
      #
      #   foo bar   --> "foo", "bar"
      #   "foo bar" --> "foo bar"
      #   foo\"bar  --> "foo\"bar"
      #
      # Invoking genargs.pl with -comma will print an initial comma if
      # there's anything to print at all.
      #
      # Sample application in a Makefile:
      #  HSIFIED_EXTRA_LD_OPTS= `echo "$(EXTRA_LD_OPTS)" | $(PERL) genargs.pl`
      #  PACKAGE_CPP_OPTS += -DHSIFIED_EXTRA_LD_OPTS="$(HSIFIED_EXTRA_LD_OPTS)"

      	Add support for Ross Paterson's arrow notation
      	----------------------------------------------
      
      Ross Paterson's ICFP'01 paper described syntax to support John Hughes's
      "arrows", rather as do-notation supports monads.  Except that do-notation is
      relatively modest -- you can write monads by hand without much trouble --
      whereas arrow-notation is more-or-less essential for writing arrow programs.
      It desugars to a massive pile of tuple construction and selection!
      
      For some time, Ross has had a pre-processor for arrow notation, but the
      resulting type error messages (reported in terms of the desugared code)
      are impenetrable.  This commit integrates the syntax into GHC.  The
      type error messages almost certainly still require tuning, but they should
      be better than with the pre-processor.
      
      Main syntactic changes (enabled with -farrows)
      
         exp ::= ... | proc pat -> cmd
      
         cmd ::= exp1 -<  exp2   |  exp1 >-  exp2
      	|  exp1 -<< exp2   |  exp1 >>- exp2
      	| \ pat1 .. patn -> cmd
      	| let decls in cmd
      	| if exp then cmd1 else cmd2
      	| do { cstmt1 .. cstmtn ; cmd }
      	| (| exp |) cmd1 .. cmdn
      	| cmd1 qop cmd2
      	| case exp of { calts }
      
         cstmt :: = let decls
      	 |   pat <- cmd
      	 |   rec { cstmt1 .. cstmtn }
      	 |   cmd
      
      New keywords and symbols:
      	proc rec
      	-<   >-   -<<   >>-
      	(|  |)
      
      The do-notation in cmds was not described in Ross's ICFP'01 paper; instead
      it's in his chapter in The Fun of Programming (Plagrave 2003).
      
      The four arrow-tail forms (-<) etc cover
        (a) which order the pices come in (-<  vs  >-), and
        (b) whether the locally bound variables can be used in the
      		arrow part (-<  vs  -<<) .
      In previous presentations, the higher-order-ness (b) was inferred,
      but it makes a big difference to the typing required so it seems more
      consistent to be explicit.
      
      The 'rec' form is also available in do-notation:
        * you can use 'rec' in an ordinary do, with the obvious meaning
        * using 'mdo' just says "infer the minimal recs"
      
      
      Still to do
      ~~~~~~~~~~~
      Top priority is the user manual.
      
      The implementation still lacks an implementation of
      the case form of cmd.
      
      
      Implementation notes
      ~~~~~~~~~~~~~~~~~~~~
      Cmds are parsed, and indeed renamed, as expressions.  The type checker
      distinguishes the two.
