Save a few bytes by ommitting the static link field on closures with
an empty SRT.

HPUX fixes.

Pass -fcompiling-prelude through.

-fcompiling-prelude is back!

When compiling the Prelude we need to distinguish between wired-in
module references that are DLL-bound or not. (Just having -static
didn't cut it in the end, since it also encompasses RTS references.)

On platforms that don't use Win32 DLLs, Preludes compiled with and
without -fcompiling-prelude will be observationally equivalent.

Fix a small bug in weak ptr support.

After 'make install' has completed, make sure we regenerate the
script in a state that's useable.

Last commit made empty where bodies illegal, i.e.,

  x = 2 where

Re-added support for this "feature".

Some Haskell98-related regression tests

Neural network regression test app; contains painfully long list of
constants.

Put mkdependHS in libexecdir, not bindir.

Now lives in ghc/interpreter/lib, along with other libraries.

Handle CAF_UNENTERED (ie, reverted) in scavenge_mut_once_list

Many improvements resulting from first attempt to run nofib suite:
-- More libraries (lib/*.hs) brought into operation
-- Prelude error handling and basic I/O improved
-- Changed bytecode immediate value fields so large constant
--   tables can be compiled
-- Fixed bugs: translation of FATBAR, negative floating point
--   literals, strict constructors, handling of CAFs

#ifdeffery to make it work with interpreter.

Include CAF_ENTEREDs on the mutables list so they get scavenged correctly.

Fix bug in mkRegLiveness causing bogus heap checks to be generated on the Sparc.

docfix

enlargeStablePtrTable: initialise the whole table (incl. index 0) the first
time around.

s/show/showSDoc/

Discovered-by: removing instance Show (->) :-)

More counters reinstated; this should be the lot now:
  ENT_AP_UPD_ctr, ENT_BH_ctr, RET_UNBOXED_TUP_ctr, RET_UNBOXED_TUP_hst[]

Counter UPD_PAP_IN_PLACE_ctr erroneously missed from raw Ticky dump.

Support for unsafely thawing your (Byte)Arrays, i.e., added the
following ops:

 MutableArray.unsafeThawArray :: Ix ix => Array ix elt -> ST s (MutableArray s ix elt)
 MutableArray.unsafeThawByteArray :: Ix ix => ByteArray ix -> ST s (MutableByteArray s ix)
 MutableArray.thawByteArray :: Ix ix => ByteArray ix -> ST s (MutableByteArray s ix)

 ST.unsafeThawSTArray 	    :: Ix ix => Array ix elt -> ST s (STArray s ix elt)
 LazyST.unsafeThawSTArray   :: Ix ix => Array ix elt -> ST s (STArray s ix elt)

 IOExts.unsafeFreezeIOArray :: Ix ix => IOArray ix elt -> IO (Array ix elt)
 IOExts.unsafeThawIOArray   :: Ix ix => Array ix elt -> IO (IOArray ix elt)

+ removed the re-exportation of Monad that ST and LazyST did.

Remove the Show instance for (a->b). It will not be missed..

Top-level non-updatable thunks get closure type FUN_STATIC, not
THUNK_STATIC.  (helps the garbage collector decide where the static
link field should be).

Make type substitution strict.  This partially fixes the space leak,
and seems to improve performance marginally.

more cygwin tweakage, this time for b19

Previous mingw32 related commit upset things on the cygwin side.

Amalgamated pp.c into stg.c.

DLL_IMPORT_DATA_VAR fix

Define HEAP_ALLOCED macro in non Win32 DLL land too

COMPILING_RTS is now defined when compiling the rts. It is used for
the following:

 - the contents of includes/Prelude.h is only visible when COMPILING_RTS
   is on.
 - getting the DLLIMPORT declarations right on various labels defined by
   the Prelude or the RTS.

Win32 DLL tweaks

rts_get*: peer through indirections, if needs be.

Extend the reaches of #ifdef INTERPRETER a little bit.

StgNat64 --> StgWord64

- moved the Bool closure table to here (don't want to end up accidentally mangling it.)
- startupHaskell: for Win32 DLLs, initialise the various closure tables now that
  the DLLs have been loaded and the closure addresses are in scope.

StgNat* --> StgWord*

remove unused include + macros

Added is_heap_alloced() to the API - returns true if an address is
within the range of addresses that we've been given back from the
OS.

Only needed for Win32 DLLs, so it's only defined when compiling up
a Win32 RTS DLL.
