Merge before-ghci -> before-ghci-branch-merged in the non-ghc parts of
the tree.

Cleaning up the configuration/build process.

  - New build.mk option: GhcWithInterpreter. It has reasonable
    defaults, and shouldn't need to be overriden (you get the interpreter
    if you're bootstrapping with ghc 4.09+ on an ELF architecture, at
    the moment).

  - compilation manager now lives in compiler/compMan.  compiler/ghci
    contains only interpreter-related files.

  - WithGhcHc has gone, it now defaults to $(GHC).  This is so that
    we can reliably determine the version of $(GHC) using the stuff that
    configure tells us.  configure gets a new --with-ghc option so you
    can specify which ghc to use.

Make sure windows.h is always checked for, not just when HOpenGL is present.

First (awkward) steps towards an HOpenGL integration

comment update

look for GMP 3, not GMP 2.

Port to OpenBSD from Thomas Nordin.  Please merge with 4.08 (you'll also
need the new config.guess and config.sub from the previous commit).

added Debian location to DocBook catalog test

New autoconf tests for ghc version from Michael Weber, with minor
modifications by me.

Check the version of the installed ghc, and set GhcVersion,
GhcMajVersion, GhcMinVersion and GhcPatchLevel make variables.

Add test for GNU regex in libc, which we'll use to decide whether to
compile our own copy of the library in package text.

Quick workaround for Reuben's M$ configuration problems

autoconf hackery for CTypes{,ISO}

The DocBook saga continues: Look for already installed catalog first.

Autoconf magic to determine a working DocBook CATALOG file (if any).  Makes
the makefile variable DOCBOOK_CATALOG refer to this CATALOG file (absolute
path).

Add JadeCmd to find path of jade.

Changed Perl test so that it simply allows vv5 & 6 and disallows any other;
also hardwire path to perl to /bin/perl under Windows, to avoid clashing with
other weird Perls that may be on the path.

/tmp/msg

added autoconf magic for integral limits

Added FIND as a symbol so that it can be changed on OSes which have
different ideas as to what "find" should do.

remove duplicate signal type test.

add -ltermcap when looking for -lreadline.

From: Michael Weber.

Sven's first autoheader commandment: Don't change config.h.in manually...!
(Why is mk/config.h.in in the repository? configure is not, either.)

Added more SIZEOF/ALIGNMENT tests

urk, Solaris sh doesn't understand [^0-9] in patterns, it seems.

Added autoconf magic for size/alignment of some more C types

- FreeBSD 3+ is now known as i386-unknown-freebsd (to accomodate
  forthcoming FreeBSD 4.X

-  add alpha-unknown-{linux,freebsd}

Automatically detect installed copies of ghc, nhc and hbc and plug
them into the Makefile variables $(GHC), $(NHC) and $(HBC)
respectively.  $(HC) is now supposed to be a generic installed haskell
compiler, which defaults to $(GHC) and can be changed via ./configure
--with-hc=<blah>.

Reorganise and tidy up a few things in config.mk.in.

Package local configuration scripts allow to modularise the configuration (we
start by having one for ghc):
* Modularised configuration avoids unnecessary dependencies for individual
  packages.
* Furthermore, package local configuration (such as entering version
  information into rpm .spec files) is possible.

Make <readline/history.h> a requirement for use of libreadline.

Pass flag -ltermcap as link option for test -lreadline.

Add checks for readline library (as opposed to headers).

Add a test for libreadline.{a|so}  (include/readline/readline.h
is already tested for.).

--with-ghc-hc is now --with-hc (to be used as the "locally installed
Haskell compiler" for all projects).

Don't attempt to discover the exact location of cpp, instead use 'gcc
-E'.  With the right combination of flags, it seems we can get the
same behaviour as calling cpp directly.

Check for presence of winsock.h

New option: --enable-win32-dlls

Added `timezone' config test.

Prepared to support i?86-*-mingw32

Move 4.01 onto the main trunk.
