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.

remove unnecessary parens

Add -mno-cygwin to CPP rather than CPPFLAGS, so that it gets into mkdependC
and the like.

Add -mno-cygwin to CPPFLAGS on i386-unknown-mingw32 to stop configure.h
getting lots of bogus headers that aren't there. I'm not at all sure why
this hasn't caused problems before...

Make LIBM be detected by autoconf.

re-order the WithHc and WithGhc tests: now if you specify
--with-ghc=<ghc>, then WithHc also gets <ghc> if you don't set it
explicitly.  Previously it got whatever ghc was in the PATH, which
would fail if there wasn't a ghc in the PATH at all.

do the dlopen() check a better way.

update the configure system to find dlopen(), whether it lives in -ldl
or in the standard C library.

I'd like to take this opportunity to throw a few bricks in the general
direction of whoever invented this godforsaken tool.

remove the message that says "now do gmake boot followed by gmake..."

platform definitions for PPC/MacOSX

Revision of Marcin's QError module

* I think, there was a rough consensus that Marcin's module provides the
  right kind of interface for handling "errno"s

* Malcolm preferred an enumeration, but Marcin made a convincing argument
  that this doesn't go well with architecture-dependent variations of "errno"

* Recoded the hsc magic into autoconf magic

* In hsc files, errno constants can be accessed directly; to provide access
  for ordinary Haskell programmer, constants for a range of common symbols are
  provided (their values are determined by configure)

* Introduced an `Errno' newtype to increase type safety

* renamed the throwIfXXX functions to throwErrnoIfXXX to have the original
  names available in the language independent MarshalError

* FIXME: We need a thread local getErrno in the RTS!

(It all compiles, but is still to be tested.)

Test for inttypes.h: Solaris' version of stdint.h

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.
