      Replace the handwritten lexer with one generated by Alex.
        - Faster than the previous lexer (about 10% of total parse time,
          depending on the token mix).
        - More correct than the previous lexer: a couple of minor wibbles
          in the syntax were fixed.
        - Completely accurate source spans for each token are now collected.
          This information isn't used yet, but it will be used to give much
          more accurate error messages in the future.
        - SrcLoc now contains a column field as well as a line number,
          although this is currently ignored when printing out SrcLocs.
        - StringBuffer is now based on a ByteArray# rather than a Ptr, which
          means that StringBuffers are now garbage collected.  Previously
          StringBuffers were hardly ever released, so a GHCi session would
          leak space as more source files were loaded in.
        - Code size reduction: Lexer.x is about the same size as the old
          Lex.lhs, but StringBuffer.lhs is significantly shorter and
          simpler.  Sadly I wasn't able to get rid of parser/Ctypes.hs

      - Document -e
      - Rearrange the documentation on "modes".  I've moved the list of
        modes from the beginning of "Using GHC", to a subsection a little
        later, and the sections describing make-mode and batch-mode are now
        further subsections of this.
      - Add missing modes to the list: -M and --mk-dll.

      Add a new command-line flag -e EXPR, which runs ghc in interactive
      mode and evaluates EXPR only before exiting.
      Also, the lexer now ignores lines beginning with "#!".  This is so
      that we can use ghc as a scripting language with Unix-style scripts
      beginning with
      #! /usr/local/bin/ghc -e main
      (well, it's not quite that simple, but I'll leave the details for the
      more enterprising hackers).

      Don't bogusly use HOST instead of BUILD or TARGET in the platform defines.

      Flesh out the platform variables, rather than bogusly setting BUILD
      and TARGET to HOST most of the time.
      This doesn't give us any better cross-compiling support, but it's a
      step in the right direction.
      Also, I added a comment describing the proper meaning of BUILD
      vs. HOST vs. TARGET, and which one to test in various parts of the
      source tree.

      Uncomment AC_SUBSTs for many of the platform variables, since I'm
      guessing that this comment doesn't apply any more:
      dnl Cannot afford all these SUBSTs (because of braindead seds w/ 99 cmd limits)

      Initial x86-64 (aka amd64) support.
      Unregisterised it works perfectly.  Registerised, I think it's almost
      there, except that I seem to be running into the known codegen bug in
      GCC with register variables (bug #7871 in the gcc bugzilla), which
      means registerised support is basically hosed until the GCC folks
      can get their act together.
      We get 8 more registers on amd64, but only 2 more callee-saves
      registers.  The calling convention seems to pass args in registers by
      default, using the previously-callee-saves %rsi and %rdi as two of the
      new arg registers.
      I think GHCi should work, since we already have 64-bit ELF support
      thanks to Mat Chapman's work on the IA64 port.  I haven't tried GHCi,
      The native code generator should be a breeze, because it's so similar
      to plain x86.

      setupRtsFlags(): don't overwrite argv[0] with its basename:
         - argv[] may not point to writeable memory
         - System.Environment.getProgName strips off the 'dirname' portion
         - Not possible to get at the untransformed argv[0] from
           Haskell code, should such a need arise.
      Uses of prog_argv[0] within the RTS has now been replaced with prog_name,
      which is the basename of prog_argv[0].

      OpenBSD's sh doesn't like the parentheses in "foo='(-1)'" so let's
      drop them. Thanks to Don for pointing this out.
