move CONST_O_BINARY detection down to libraries/base

Moved test for C/ISO types to base package, hopefully testing for all
needed headers first.

Push down the tests for errno values to the base package. There's really
no need testing for this when e.g. building Happy. :-)

Removed auto-autoreconf stuff, it doesn't really work with our
recursive autoconf setup.

standalone packages: eliminate the extraneous final comma on PACKAGE_DEPS

Implement TH ForallC constructor.

Mac OS X: Explicitly align symbol stub sections in Mach-O files; Apple's as
doesn't seem to do that in all cases.

bind acosDouble to acos(), rather than asin()

Minor changes for VS/Haskell

Updated the DocBook story

Workaround for some hhc problems

Added build dependency on mesaglut-devel (provided by freeglut-devel, too).

compile: temporarily add the directory containing the .hs file to the
include path.  This matches what compiling in one-shot mode does, and
fixes a bug whereby the _stub.h file couldn't be found when compiling
with --make.

---------------------------------
	Fix a bug in usage recording
	---------------------------------

As a result of the new stuff on hi-boot-file consistency checking, I
accidentally caused Foo.hi to record a usage line for module Foo, and
this in turn caused rather nasty bad things to happen.  In particular,
there were occasional crashes of form

ghc-6.3: panic! (the `impossible' happened, GHC version 6.3.20041017):
        forkM Constructor Var.TcTyVar{d r1B9}

At least I think that's why the crash happened.

Anyway, it was certainly a bug, and this commit fixes it.  The main
payload of this fix is in Desugar.lhs;  the rest is comments and
tidying.

Fix braino in pprAsmCLbl

GhcWithNativeCodeGen=NO for Sparc, until the old Sparc native codegen
is updated (not likely to happen soon).

Remove -static flags for alpha and hppa.
Turns out mips(el) on Linux is more complicated than first appeared, so
leaving it be for now.

Implement -fwarn-incomplete-record-updates

Fix a source location bug (by deleting a line of code!)

the splitter now supports linux/powerpc

Put the '@' suffix on stdcall ForeignLabels on Windows only.

ccallConvAttribute: use __attribute__((__stdcall__)) rather than
__stdcall (the latter is Win32-specific).

Make foreign import stdcall "dynamic" work via-C (we'd forgotten to
add the __stdcall qualifier to the type cast for the function).

Here's the 6.2.2 announcement

trivial changes to correct a build-breaker that only affects linux/powerpc

Add a SrcSpan to the DataCon in a ConPatOut.

Declare rtsSupportsBoundThreads() here.

This change should have gone through with the threaded RTS I/O changes
yesterday.

Threaded RTS improvements:

 - Unix only: implement waitRead#, waitWrite# and delay# in Haskell,
   by having a single Haskell thread (the IO manager) performing a blocking
   select() operation.  Threads communicate with the IO manager
   via channels.  This is faster than doing the select() in the RTS,
   because we only restart the select() when a new request arrives,
   rather than each time around the scheduler.

   On Windows we just make blocking IO calls, we don't have a fancy IO
   manager (yet).

 - Simplify the scheduler for the threaded RTS, now that we don't have
   to wait for IO in the scheduler loop.

 - Remove detectBlackHoles(), which isn't used now (not sure how long
   this has been unused for... perhaps it was needed back when main threads
   used to be GC roots, so we had to check for blackholes manually rather
   than relying on the GC.)

Signals aren't quite right in the threaded RTS.  In fact, they're
slightly worse than before, because the thread receiving signals might
be blocked in a C call - previously there always be another thread
stuck in awaitEvent() that would notice the signal, but that's not
true now.  I can't see an easy fix yet.

Undo part of previous commit, a little testing code sneaked in and
broke all the GHCi tests.

Had enough of 'make boot' completely rebuilding gmp/ each time around.

---------------------------------
	Add lists to valid derivable methods
	---------------------------------

	(It'd be nice to merge this into the stable
	branch. It is an increase in functionality, but
	it's quite separate from everything else.)

Lists are useful in derivable type classes.  E.g. methods like

	class Shrinkable a where
	  op :: a -> [a]

This commit adds them, to join functions and tuples.

Remove dead code tcSplitMethodTy

---------------------------------
	Fix bug in derivable type classes
	---------------------------------

		MERGE TO STABLE (if poss)

The test for not-supported method types for derivable type classes
was broken. This fixes it.

Fixes to readline detection and use.
VS: ----------------------------------------------------------------------

Detect whether $(GHC) supports the readline package.

Fix typo; fixes simpl007

genericRaise() hack needed on FreeBSD too.
