New file for RTS->Prelude dependencies.

Handle references from the RTS to the Prelude in a more consistent
way.

	- For statically-linked binaries, nothing has changed.

	- For the interpreter, refs from the RTS to the Prelude
	  are now indirected.  The indirections need to be
	  filled in at some point during startup by calling
	  fixupPreludeRefs (in Prelude.c).

	- The CHARLIKE and INTLIKE tables are now handled in
	  the same way for both Hugs and DLLs.

Hugs will be broken for a short while until Julian sorts out the Hugs
parts of this change.

oops, missed one instance of UnsafeThawByteArrayOp.

Fixed recent -syslib com buglet

mingw32: do as for cygwin platforms & default the name of the generated
binary to main.exe if -o <...> isn't given.

Simplified prog_* externs a little

Misc Win32 bitrot

Don't be selective about what's exported from the RTS DLL any more,
as it requires sync'ing HSrts.def whenever the RTS offerings change.

* 'inlined' subset of the MM protos needed to compile this module, i.e.,
  don't require whoever does a 'make' in ghc/rts/ to have extended their
  <windows.h>
* right Win32 proto for handle_tick()

Support for setting target-specific CC options via AC_SUBST (and make use
of it on the mingw32 front -- 'resist' the temptation to use GMP's config/
story for this.)

mingw32 support

remove some Makefile debugging bits

When booting, pass in --target to gmp/

#include wibbles.

Win32 wibble.

Track recent re-homing of Prelude.h for INTERPRETER.

Remove unsafeThawByteArray# primop (which was a no-op), and use
unsafeCoerce# instead.

remove duplicate signal type test.

Add PutFullMVar test

Further cleanups of connect.h.  Also, zap the Args macro.  We really
don't need to support K&R C any more.

Need to pull in PutFullMVar from PrelException.

Disable the stuff that was supposed to lex octal & hexadecimal
literals, but which didn't work.  The code in the Haskell report
doesn't attempt to lex these either.

Add new exception: PutFullMVar for putting into an already full MVar.

Move Prelude.h from ghc/includes into ghc/rts.  It's essentially a
list of the things from the Prelude that the RTS depends on, and isn't
relevant to STG code.  Furthermore, this helps to clarify which parts
of the RTS depend on things from the Prelude (by an explicity
#include).

Clean up a couple of compilation warnings.

Remove #ifdef STANDALONE_INTEGER.

Pick up the pieces after Sven's Saturday Night Fever :)

remove unused gunk.

Remove duplicate definition of unblockOne.

Reset the interrupted flag after an interruption.  This allows
finalizers to run, and means that Hugs doesn't get stuck in an
interruption loop.

Saturday Night Fever: hPutBufBA again... >:-(

Removing backend.h for Julian.

Update .c files to reflect reorganisation of .h files in this directory.

Major cleanup of header files.  Merge the 5 deleted files into connect.h.
Organise connect.h to gather declarations into roughtly related
categories.

Nuke a substantial number of no-longer-supported options.

First stab at reviving TREX - just fixing some header wibbles.  Also one small
fix to get implicit parameters working (`textOf' needed to be taught that
IPCELLs are also OK).  Moved #defines for TREX, IPARAM, etc, into options.h
(in their previous location at the end of prelude.h, they were being defined
too late).

Fix h{Fill,Put}Buf(BA)?.  They now work in the presence of
partial/blocking reads and writes, and hPutBuf now doesn't hold on to
the handle while it's blocking.

Fix h{Fill,Put}Buf(BA)?.  They now work in the presence of
partial/blocking reads and writes, and hPutBuf now doesn't hold on to
the handle while it's blocking.

Compilation cleanups:
* Add some prototypes to header files, to avoid compilation warnings.
* Remove irrelevant #ifdeffery (#if NPLUSK, + various others)

Rm debugging printf.
