      Mac OS X:
      Make the Linker deal properly with object files that lack a symbol table or
      a dynamic symbol table.
      Objects that don't import any symbols don't get a dynamic symbol table,
      which caused GHCi to crash.

      Improved #include path handling:
      * Don't use '-I-', it breaks a lot of system headers, e.g.
           #include <GL/glut.h>
        fails (when using freeglut), because /usr/include/GL/glut.h contains
           #include "freeglut_std.h"
        but /usr/include/GL/freeglut_std.h will not be found. It is a bit
        debatable if the header is broken and should use
           #include "GL/freeglut_std.h"
        instead. Anyway, a grep through the SuSE 9.1 system headers shows that
        there seems to be no real common practice, so let's play safe and don't
        use '-I-'.
      * Don't use '-I .', #include stub headers "locally" instead, e.g. use
           #include "Concurrent_stub.h"
        instead of
           #include "Control/Concurrent_stub.h"
        Note that "Control" is still in the #include path, because the *.hc file
        is normally in /tmp and the stub header is in the directory where *.hs
        is. We could remove this path element, too, if the stub header would be
        copied to the directory of the *.hc file during compilation. SimonM?

      Make sure genericRaise symbol is defined on all platforms, so Linker.c
      won't complain, even if they don't actually use it.

      When linking against libpthreads, raise(3) can behave strangely on
      some platforms (OpenBSD at least, maybe other BSDs, not Linux). So use
      pthread_kill() to generate signals when running the threaded rts,
      instead of raise(), when System.Posix.Signals.raiseSignal is called.
      raiseSignal will call genericRaise, in the rts, which knows which
      function to use.

      	Simplify the treatment of newtypes
      	Complete hi-boot file consistency checking
      In the representation of types, newtypes used to have a special constructor
      all to themselves, very like TyConApp, called NewTcApp.    The trouble is
      that means we have to *know* when a newtype is a newtype, and in an hi-boot
      context we may not -- the data type might be declared as
      	data T
      in the hi-boot file, but as
      	newtype T = ...
      in the source file.  In GHCi, which accumulates stuff from multiple compiles,
      this makes a difference.
      So I've nuked NewTcApp.  Newtypes are represented using TyConApps again. This
      turned out to reduce the total amount of code, and simplify the Type data type,
      which is all to the good.
      This commit also fixes a few things in the hi-boot consistency checking

      	Do simple checking on hi-boot files
      This commit arranges that, when compiling A.hs, we compare
      the types we infer with those in A.hi-boot, if the latter 
      exists.  (Or, more accurately, if anything A.hs imports in
      turn imports A.hi-boot, directly or indirectly.)
      This has been on the to-do list forever.

      Replace \? by \{0,1\} in the sed regular expressions, as the former
      does not work with Mac OS X's (= BSD's) sed.
      I'm a bit confused by the situation here:
      According to Mac OS X man pages, the latter syntax is part of the
      POSIX 1003.2 standard for basic regular expressions, while the former
      is not. According to the manpage installed with my Gentoo linux, neither
      is in the POSIX standard.
      However, GNU sed accepts both \? and \{0,1\}, while Mac OS X's sed accepts
      only \{0,1\}.

      	Add Generalised Algebraic Data Types
      This rather big commit adds support for GADTs.  For example,
          data Term a where
       	  Lit :: Int -> Term Int
      	  App :: Term (a->b) -> Term a -> Term b
      	  If  :: Term Bool -> Term a -> Term a
          eval :: Term a -> a
          eval (Lit i) = i
          eval (App a b) = eval a (eval b)
          eval (If p q r) | eval p    = eval q
          		    | otherwise = eval r
      Lots and lots of of related changes throughout the compiler to make
      this fit nicely.
      One important change, only loosely related to GADTs, is that skolem
      constants in the typechecker are genuinely immutable and constant, so
      we often get better error messages from the type checker.  See
      There's a new module types/Unify.lhs, which has purely-functional
      unification and matching for Type. This is used both in the typechecker
      (for type refinement of GADTs) and in Core Lint (also for type refinement).

      Add -I- after the include paths when running gcc.  This prevents
      accidental shadowing of system includes by putting a file called
      eg. stdint.h in the current directory.

      rts_evalStableIO: set rtsApiCapability to NULL *before* calling
      scheduleWaitThread, matching the way the other eval_* functions do
      The previous way lead to a suble race condition:
        - thread A calls rts_evalIO, enters scheduleWaitThread()
          (rtsApiCapability == NULL).
        - thread B calls rts_evalStableIO, creates a main thread and enters
          scheduleWaitThread() (rtsApiCapability == &MainCapability)
        - thread A exits scheduleWaitThread, sees that rtsApiCapability is
          non-NULL, and calls releaseCapability() on it.  This is bogus,
          because thread A doesn't actually hold the capability, and we've
          done a double-release.
      This scenario leads to assertion failures in a debug threaded RTS, and
      probably crashes in a non-debug threaded RTS.
