Make the new Posix bindings compile on Mac OS X.
Most notable, Mac OS X lacks
*) lchown
*) SIGPOLL
I don't know of a replacement of either, so they are just left out when
they are not detected by configure.

Make it compile for Mac OS X again.

The never-ending docbook tragedy: Adapt the catalogs once more... >:-P
NOTE: I don't really have a clue what I'm doing here, but at least it
works with the current SuSE Linux distribution 8.1.

Warning police #13: Sync fprintf format strings with args in an
architecture-neutral way.

Warning police #12: Multi-line string literals are uncool.

PowerPC Mach-O:
Handle more kinds of relocations, so that non-PIC-code can be loaded

PowerPC-related changes:
Use proper register names for floating-point registers
Define SpillTmp registers for NCG

typos never end.

typo

wibbles on mdo-documentation

Wibble in loading of boot interfaces

MonadRec => MonadFix changes

get mfix from Control.Monad.Fix

Better derived Ord code

Use the ModSummary fields in record construction

The help text for the -i profiling option was wrong: it claimed the
argument was in milliseconds rather than seconds.

MERGE TO STABLE

Move mdo section

Minor wibble

.PHONY: package-way-dist

wibble in dist-manifest rule (writing to MANIFEST.tmp isn't necessary
and may hide errors)

Don't bother with the $@.tmp hack in the rule for building libraries,
.DELETE_ON_ERROR (in suffix.mk) should do the job for us.

s/rm -f/$(RM)

Use $(RM) rather than explicit 'rm -f'

Set .DELETE_ON_ERROR rather than using the strange construction

	<command> || ($(RM) $@; exit 1)

in a few places.

Replace
	.PRECIOUS: %.hs
with
	.SECONDARY: %.hs

.PRECIOUS is the wrong thing: it keeps the file when 'make' is
killed, as well as preventing automatic deletion.  .SECONDARY just
prevents the automatic deletion.

Spotted by: Ian Lynagh.

Fix cut-n-pasto

$(EXE_SUFFIX) duplicates $(exeext), and the latter seems to be more
widely used, so nuke the former.

Remove unused $(PRINTER)

clarifications on the mdo documentation.

documentation for the mdo-notation.

(I've run this through jade, no syntax errors, but couldn't get
any html output as my docbook installation is a bit weird: couldn't
find style-files etc. it'll be great if someone can run it through
to make sure what I added looks acceptable..)

get mfix from MonadRec

make sure we get the name right when we call doStmtListErr

Wibbles to improve error reporting

--------------------------------
        Implement recursive do-notation
	--------------------------------

This commit adds recursive do-notation, which Hugs has had for some time.

	mdo { x <- foo y ;
	      y <- baz x ;
	      return (y,x) }

turns into

	do { (x,y) <- mfix (\~(x,y) -> do { x <- foo y;
					    y <- baz x }) ;
	     return (y,x) }

This is all based on work by Levent Erkok and John Lanuchbury.

The really tricky bit is in the renamer (RnExpr.rnMDoStmts) where
we break things up into minimal segments.  The rest is easy, including
the type checker.

Levent laid the groundwork, and Simon finished it off. Needless to say,
I couldn't resist tidying up other stuff, so there's no guaranteed I
have not broken something.

--------------------------------
     Do type-checking of external-core input
	--------------------------------

When we read in an External Core file, we should really type-check it.
We weren't, because we treated it as if it were trusted, interface-file
material.

This commit fixes the problem, albeit in a bit of a hacky way.  The
typechecking is done by Lint, which does not give as friendly error
messages as does the normal typechecker.  But it's much better than nothing.

I also removed the entirely-unused 'warnings' from the Lint monad.

Fix case of C {} for non-record constructor C, but with strict fields

Fix egregious loop error

In 'make html', bale out with a useful message if Haddock is not installed.
