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.

Emit soothing msg to counter the (harmless) autoconf warning that is output while processing AC_C_BIGENDIAN

Added f-checks for symlink() and readlink()

Added tests required by Hugs

Default WithGhcHc is now just "ghc".  Too many people complained.

Add support for FreeBSD 3.0 (ELFish).
Rename i386-unknown-freebsd to i386-unknown-freebsd2, and add
i386-unknown-freebsd3.

NOTE: this won't bootstrap an ELF GHC using an a.out GHC, some laying
on of hands is required for that.

added use of FPTOOLS_CODE_BEFORE_DATA, FPTOOLS_END_DATA_SECTION, FPTOOLS_END_TEXT_SECTION

Tidied up a bit + added --with-ghc-hc option

Doc string for --enable-hc-boot was lacking; added --with-gcc cmd line option

check for netinet/tcp.h (apparently needed for some socket options on
FreeBSD).

Oops, last commit left out this file

Check if (struct stat) has st_blksize

apparently GMP is installed as libgmp2.a on Debian systems.
