Turn off splitting on x86_64

enable x86_64 native codegen

oops, undo accidental enabling of x86_64 native codegen

Refine the default setting for GhcWithInterpreter, now exludes x86_64
for the time being.

Mac OS X:
Kill HaskellSupport.framework.
Instead, look for GMP.framework (a framework-version of libgmp), else look
for a normal -lgmp as usual.
The other part of HaskellSupport.framework, dlcompat, is no longer needed
(as of Mac OS X 10.3, it's included in libSystem).
It's enough to just use the normal configure tests for -ldl.

	Merge to STABLE

This commit switches off the generation of the support code for 'Derivable
Type Classes' by default.  Use -fgenerics to switch it on.

Motivation: seldom used, and there's a nasty blowup in Core types for data
types that have lots of constructors or lots of fields.

We now put -fgenerics in the GhcLibOpts, so that the libraries have the
support code, as before.

more regex test down to libraries/base

Comment updates only (platform-related)

Add way debug_u

Work around problems caused by limit on the length of the command line
in ld, which shows up when building OpenGL on Windows with SplitObjs=YES.

We now pass the names of the input files to ld via a linker script.
This is (probably) only supported by GNU ld, so we now have to detect
GNU ld in the configure script (yawn) and back off to the old method
if we don't have it.

Moved GTK_CONFIG detection to ghc subdirectory (untested).

Nuked some outdated stuff

Make the X11 and HGL packages more independent, and pass configuration
parameters to package.conf.in via header files.

Also removed residual traces of OpenGL/GLUT/OpenAL from mk/config.mk.in

Fix previous commit:
Don't handle Solaris2-flag _POSIX_PTHREAD_SEMANTICS in configure at all
but simply #ifdef solaris2_TARGET_OS #define ... it in the header-file.

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

Detect whether $(GHC) supports the readline package.

Re-nuked SGML support, I crept back in with a previous commit. >:-(

Nuked SGMLDocWays

Rationalise the install settings a bit.  Before, if you had $OWNER or
$GROUP set in your environment, then these would lead to options being
given to install, possibly with unexpected results.  This caused
install to fail for at least one person.

Now, $(INSTALL_OWNER) and $(INSTALL_GROUP) are set via
config.mk/build.mk as with other settings.

SGML is dead, long live DocBook XML!

Note: The BuildRequires tags in the spec files are still incomplete
and the documentation about the DocBook tools needs to be updated,
too. Stay tuned...

* Factored out labeling options (used by FO now, too)
* Cleaned up stylesheet handling

<fanfare>Finally: Support for DocBook XML!</fanfare>

After endless frustrating hours, I came to the conclusion that using (Open)Jade
for DocBook XML is virtually impossible, there are *tons* of problems with it:
Wildly differing paths, incorrect stylesheets, broken catalogs at funny places,
broken wrapper scripts, missing support on Cygwin etc.  >:-P * * *

So we follow the ubiquitous XSL hype and use xsltproc + DocBook XSL stylesheets
to transform DocBook XML to HTML and FO. From FO there are two routes to PDF and
PostScript: Either via FOP (preferred) or via PassiveTeX. Validation can be done
via xmllint using the new make target "validate". When PassiveTeX is available,
DVI can be generated, too.  A new make target "no-chunks-html" is available for
generating an all-in-one HTML document. Currently there is no way to generate
plain text or RTF, but at least the former could easily be added.

Generating HTML works out-of-the-box on Cygwin now, but you will have to install
FOP for other formats, because there seems to be no standard package for it.

The HTML appearance can be controlled via CSS, but the current location of the
master stylesheet below fptools/mk is a bit debatable. Better suggestions are
welcome.

Currently there is still support for SGML documents, but it will be dropped when
all documents are converted to DocBook XML. The build system is complex enough
already with the support for a *single* kind of DocBook...

Windows fixes.  There were some strange things going on with Windows
installation directories - I'm sure I've mucked up whatever was
happening with 'make install' for GHC on Windows, but there were
defintitely some bugs in here.  eg. we shouldn't have been setting
datadir to $(prefix)/imports unconditionally on Windows.

Make install now works for Happy, Alex and Haddock.  GHC probably
needs a bit of tweaking to get it working again.

Add $(Windows), which is "YES" if the host platform is a Windows
platform (mingw32 or cygwin32), and "NO" otherwise.

"make dvi ps html" in $(TOP) builds *all* documentation now

Install MinGW32 gcc and perl.

Windows make install sees an eagle.  It's heart aches - one day it will soar.

Remove GhcRtsThreaded - there's no reason to leave it in this file.

if X is available, build X11 and HGL packages.

add a few RTS ways (combinations) I missed out

Update docs for RTS options and GhcRtsThreaded

Allow configuration of RTS ways by tweaking the GhcRTSWays variable.
Add default settings to config.mk.in, and add a comment to explain
which values make sense here.

Also, I disabled the debug_p way by default; it's of limited
usefulness to the average punter.

Add +RTS -K2m to SRC_HAPPY_OPTS, to work around perf. problems in the HEAD.

Completely overhauled OpenGL/GLUT detection magic, making things more
modular. Removed support for Mesa and non-HW-accelerated support on
Windoze. Added initial support for handling missing glut.h header on
MinGW/MSYS (to be completed). Tested on Cygwin (plain, -mno-cygwin,
--without-x), MSYS/MinGW and SuSE 8.2 x86 Linux.

Added the first pieces of an OpenAL binding which has been of my disk for quite
a while. Note that it is built by default when a usable OpenAL library is found,
but this could be disabled via --disable-openal on the configure commandline.
Similar behaviour should probably be the default for all optional libraries.
Note that I have created a new hierarchy rooted at "Sound", the existing
hierarchies didn't fit.

* Cleaned up test for GTK_CONFIG
* Nuked unused GTK_VERSION

Some steps towards decoupling the OpenGL and GLUT packages

Cleaned up the mechanism for building the unix package

For consistency reasons, rename HaveReadlineHeaders to GhcLibsWithReadline
