Alex / Frown

Added a new Alex template to copperbox/tools/alex_frown that has prettier error messages (at the expense of tracking more state).

Frown: c2hs parser

I have been working on a Frown version of the c2hs C Parser. This is the initial check-in.

The code compiles though the parser has no actions, so it does not build a parse tree. The lexer is also incomplete - white space is the most obvious omission. Getting the code to compile has been over 4 days work, so I'm commiting this draft now.

GHC is taxed by the code that Frown generates. In particular Frown's compact format will not compile even though the code is smaller - the absence of type signatures on such a large file makes trouble for GHC's type inferencing.

Tidied up the 'Compiler' a bit, but it still needs more work to make it something approaching comprehensible. Added LambdaCore a 'typed intermediate language' that will hopefully make code generation easier (we shall see...).

Changes to the makefile. The makefile used to do elaborate things in the Gen directory, now it doesn't. Instead components look after their own construction.

NuevoAsdl updated. Initial work to simplify the 'compiler' and Haskell code generation.
