      Darwin / Mac OS X:
      
      For builds with dynamic libraries, fix up dynamic library paths
      ("install names") for binaries. Otherwise, a dynamically-linked stage2 ghc
      would contain the path names of the build directories.

      In the installed package.conf, all includeDirs were empty, so no GHC/package
      headers were found. This commit fixes that (in a hopefully correct way).

      Add support for the dead code stripping feature of recent Apple linkers.
      If your code is compiled using the NCG, you can now specify
      -optl-W,-dead_strip on the GHC command line when linking.
      It will have basically the same effect as using split-objs to build the
      libraries.
      
      Advantages over split-objs:
          * No evil perl script involved
          * Requires no special handling when building libraries
      
      Disadvantages:
          * The current version of Apple's linker is slow when given the
            -dead_strip flag. _REALLY_ slow.
          * Mac OS X only.
      
      This works by making the NCG emit the .subsections_via_symbols directive.
      Additionally, we have to add an extra label at the top of every info table,
      and make sure that the entry code references it (otherwise the info table
      will be considered part of the preceding entry code).
      The mangler just removes the .subsections_via_symbols directive.

      Don't try to run finalizers at program exit.  This turned out to be
      hard if not impossible to do in general, so now we don't attempt it at
      all.
      
      The Main.main wrapper, previously called runIO and now called
      runMainIO, flushes stdout and stderr before exiting.  This should
      catch most cases where programs rely on Handles being flushed at
      program exit, but note that now if you simply drop a Handle in your
      program, there's no guarantee it'll be flushed on exit.  If the
      punters complain enough, I suppose we could implement a global
      Handle table and flush them all at exit... I'd rather not do this if
      possible, though.  Better to teach people to close their Handles
      properly.

      Fill in the haddock-interfaces and haddock-html fields in the
      package.conf files.
      
      To do this I had to make some changes:
      
        - haddock-interfaces requires the value of $(datadir).  We can't
          just plug this in, because $(datadir) might change at install-time
          (eg. a Windows installer can be placed anywhere, as can a Unix
          binary .tar.gz distribution).  The current trick is for the
          compiler to splice in the value of $libdir in package.conf at
          runtime.  So we could extend this mechanism and tell the compiler
          the value of $datadir via a command-line option, but that seems
          ugly.
      
          On Windows, $datadir==$libdir, so we don't need any changes:
          package.conf still uses $libdir, and a Windows installation is
          independent of its absolute location.  Even 'make install' on
          Windows should have this property.
      
          On Unix:
      	- for 'make install' and in-place execution, we just use
                absolute paths in package.conf
      
      	- for a binary dist, we generate a package.conf that refers
      	  to $libdir and $datadir, and splice in the values at
      	  install-time (distrib/Makefile-bin.in).
      
        - Also, I renamed $libdir to $topdir to more closely reflect its
          actual meaning.  This is somewhat malicious in that it will flush
          out all those clients using $libdir when they really shouldn't
          be :-)

      USE_MMAP on Linux too: this is needed for sparc64-unknown-linux at
      least, and since it seems to work on i386-unknown-linux too we might
      as well enable it.  We should probably use it on more arches/OSs too.

      ------------------------
          Reorganisation of hi-boot files
        	------------------------
      
      The main point of this commit is to arrange that in the Compilation
      Manager's dependendency graph, hi-boot files are proper nodes. This
      is important to make sure that we compile everything in the right
      order.  It's a step towards hs-boot files.
      
      * The fundamental change is that CompManager.ModSummary has a new
        field, ms_boot :: IsBootInterface
      
        I also tided up CompManager a bit.  No change to the Basic Plan.
      
        ModSummary is now exported abstractly from CompManager (was concrete)
      
      * Hi-boot files now have import declarations.  The idea is they are
        compulsory, so that the dependency analyser can find them
      
      * I changed an invariant: the Compilation Manager used to ensure that
        hscMain was given a HomePackageTable only for the modules 'below' the
        one being compiled.  This was really only important for instances and
        rules, and it was a bit inconvenient.  So I moved the filter to the
        compiler itself: see HscTypes.hptInstances and hptRules.
      
      * Module Packages.hs now defines
          data PackageIdH
          = HomePackage 		-- The "home" package is the package
       				-- curently being compiled
          | ExtPackage PackageId	-- An "external" package is any other package
      
         It was just a Maybe type before, so this makes it a bit clearer.
      
      * I tried to add a bit better location info to the IfM monad, so that
        errors in interfaces come with a slightly more helpful error message.
        See the if_loc field in TcRnTypes --- and follow-on consequences
      
      * Changed Either to Maybes.MaybeErr in a couple of places (more perspicuous)

      A first stab at position independent code generation for i386-linux.
      It doesn't work yet, but it shouldn't break anything.
      
      What we need now is one or both of the following:
      a) A volunteer to implement PIC for x86 -fvia-C
          (I definitely refuse to touch any piece of code that contains
           both Perl and x86 assembly).
      b) A volunteer to improve the NCG to the point where it can compile
         the RTS (so we won't need point a).

      When -dynamic is specified but -fPIC is not, generate code that works around
      the ELF dynamic linker's misguided attempts to keep the main program unaware
      of dynamic linking.
      
      This involves generating indirect references and computed jumps for position
      dependent code, too, and making all constant data sections writable in order
      to persuade ld to not use "COPY" relocations.
      
      Tested on powerpc-linux; in theory, it also applies to i386-linux, but other
      parts of the PIC story are missing there.
      
      Note that the writable-const-data hack could be improved a bit by
      distinguishing between "really" constant data and "relocatable" constant data,
      which would be a nice thing to do anyway.

      HEADS UP!  You now need to use an up to date Happy from CVS to build
      GHC.  Happy version 1.15 will be released shortly.
      
      Replace the slow hacked up String-based GetImports with one based on
      the real Haskell parser.  This requires a new addition to Happy to
      support parsing partial files.  We now avoid reading each source file
      off the disk twice: once to get its module name and imports, and again
      to parse it.  Instead we just slurp it once, and cache the StringBuffer.
      
      This should result in improved startup times for ghc --make,
      especially when there are lots of source files.
