subst new variable hardtop_plat - platform-specific version of hardtop

Test for stddef.h

Nuke feature testing for misc error code values + its corresponding
CCONST_XXXX #defines.

Detect whether the local 'ld' command supports -x, and only use the
flag if it does.

Added FPTOOLS_FIND_FIND.

On Win32 boxes, rejects the MS 'find' utility and continues
searching for GNU find. On non-Win32 boxes, equal to
AC_PATH_PROG(FindCmd, find)

Don't check for an installed GHC if the user said --with-ghc=... or
GHC=... ./configure.

check for lstat()

DocBook catalog: Only prefix hardtop if we end up using a glafp-utils/docbook CATALOG

Change the story about POSIX headers in C compilation.

Until now, all C code in the RTS and library cbits has by default been
compiled with settings for POSIXness enabled, that is:
   #define _POSIX_SOURCE   1
   #define _POSIX_C_SOURCE 199309L
   #define _ISOC9X_SOURCE
If you wanted to negate this, you'd have to define NON_POSIX_SOURCE
before including headers.

This scheme has some bad effects:

* It means that ccall-unfoldings exported via interfaces from a
  module compiled with -DNON_POSIX_SOURCE may not compile when
  imported into a module which does not -DNON_POSIX_SOURCE.

* It overlaps with the feature tests we do with autoconf.

* It seems to have caused borkage in the Solaris builds for some
  considerable period of time.

The New Way is:

* The default changes to not-being-in-Posix mode.

* If you want to force a C file into Posix mode, #include as
  the **first** include the new file ghc/includes/PosixSource.h.
  Most of the RTS C sources have this include now.

* NON_POSIX_SOURCE is almost totally expunged.  Unfortunately
  we have to retain some vestiges of it in ghc/compiler so that
  modules compiled via C on Solaris using older compilers don't
  break.

Make the Time module thread-safe by calling the reentrant functions
gmtime_r and localtime_r instead of gmtime and localtime wherever
they are available.

(This is necessary to make Time work at all on our Alpha machine --
perhaps GHC tickles the reentrancy of the C library or something?)

Added "--enable-hc-boot-unregisterised" option to configure,
for bootstrapping from unregisterised HC files.

Teach configure.in to canonicalise new-fangled Alpha system names,
such as alphaev67-dec-osf5.0, to alpha-dec-osf3.

Fix a number of bugs in the autoconf setup, thanks to Gregory Wright

Fix jade detection on Windows for jades that don't understand Unix paths

Fix path for Windows jade

gcc-2.95.3-4 for mingw accepts -mwin32, so allow it

Kill --enable-minimal-unix-deps (now == mingw32) and emit an error if a
Cygwin compiler is detected.

Plumb top-level --with-gcc=... value around the place.

Tidy up the handling of -mno-cygwin.

Split up win32 tests so CPP is only updated after cpp is found

Set C and CPP flags before finding gcc

wibble

Test whether $(CC) supports -mwin32 + have configure script set SRC_CC_OPTS

NOTE: new configure.in - remember to autoconf and reconfig

I'm moving X.gc and Xlib.gc from hslibs/graphics/lib/x11 to
hslibs/xlib and integrating them into the hslibs maketree.  This lib
now lives at the same place in the hierarchy as win32 - probably not
perfect for the new library story but good enough for the old hslibs I
think.

I'm not converting them from GreenCard to hsc2hs but I think that
would be a good medium term goal.  I'd like to do it myself because
I'd like to try using hsc2hs but I can't imagine when I'll get the
time so if someone feels like doing it, go right ahead.  (The HGL
(hslibs/graphics/lib/x11) is probably the only code that depends on
the Xlib interface - so mild changes to the Xlib API would be fairly
easy to fix up.)

It all seems to build and compile (not sure about linking yet) but,
for the life of me, I can't figure out what part of the makefile calls
ghc-pkg -a so that isn't quite working yet.  (I _think_ the makefile
does this - but could be wrong.)

If someone could either point me at the relevant part of the makefile
docs or just fix it for me, I could move onto getting the graphics lib
integrated into the hslibs maketree - which would leave me with just
the Hugs part of the HGL distribution to fix before the next Hugs
release.  (If I was a good Haggis, I'd beat up on Hugs' ffi too - but
I'm a very overworked Haggis at the moment so I'm not sure I'll get
that far.)

perl config: Remove bogus test I introduced

Add -mwin32 -mno-cygwin to CPPFLAGS.

New configure script option, --enable-minimal-unix-deps, a Win32-specific
option which lets you build a compiler that doesn't depend on cygwin tools
to run. Well, you still need tools such as gcc and perl in the backend, but
these don't have to be cygwin ports.

'flex' or 'lex' is required to compile up fptools/ (e.g., reqd in
glafp-utils/sgmlverb). autoconf's standard macro AC_PROG_LEX just
defaults to 'lex' if 'flex' isn't found, but doesn't actually
check whether 'lex' is available along PATH.

Added AC_PROG_LEX_STRICT, which extends AC_PROG_LEX by checking
for the presence of 'lex' if 'flex' isn't found. It bails
out with an error message if 'lex' cannot be found.

we're only supporting NetBSD/ELF now, not a.out (Lennart's suggestion)

NetBSD <= 1.4 is a.out, apparently

Add -mwin32 -mno-cygwin to CPPFLAGS on Windows.

Plumb LibsReadline into extra_libraries for -package util, rather than
extra_ld_opts, so that GHCi knows to load them too.

add a few extra headers

Let it work on FreeBSD where fileno is a macro.
Support readline-4.2 (some C functions were renamed).
Correctly treat rl_redisplay_function as returning void.

readded Debian's old SGML catalog path for backward compat with Debian-2.2

Debian updates

Replace Readline with a more complete version.
Process .hsc files in hslibs.

Add -mwin32 for new Cygwin gcc.
