Bindists should now work again, when doing "make install" at least.
"make in-place" is probably still broken.

It used to be the case that
    autoreconf
in the root would also autoreconf in any libraries that need it, and
    ./configure
in the root would also configure all the libraries.

However, cabal now configures the libraries, so they were getting
configured twice.

Thus now a small shellscript, boot, autoreconfs the root and all libraries
that need it, and ./configure in the root doesn't configure the libraries.

* configure can be told where ld is
* make an hsc2hs-inplace.bat
* tell Setup configure about foo.bar rather than foo on Windows
* tell Setup configure to pass a --with-cc=$(CC) argument to ./configure

This avoids recomputing them via $(shell) each time make expands one
of these variables, which is very expensive (0.3s or so) on Windows.

This lets the threaded RTS use SIGVTALRM rather than SIGALRM for its
interval timer signal, so the threaded and non-threaded RTS are
compatible.  It unfortunately doesn't completely fix #850/#1156, for
that we really have to use a restartable sleep instead of usleep().

Also I cleaned up the timer API a little: instead of returning an
error value that ultimately gets ignored, we now report errors from
system calls and exit.

Previously one had to edit configure.ac to build a release version. This is
evil, so one can now specify this on the configure invocation line like:

   RELEASE=YES ./configure

Note that non-released versions are still the default.

For non-release builds, we want to append a date to the version number
(e.g. 6.7.20070206).  Previously this was done by the nightly build
script, this new method figures out the snapshot version by querying
the darcs repository and finding the date of the most recent patch
(actually it finds the most recent of the last 100 patches, but that
should be good enough).  This is done by the configure script.

To handle source distributions, we create a file VERSION in the
top-level directory that contains the version number, and ship this in
the source distribution.  The configure script picks up the version
from this file if it doesn't see a _darcs directory.

Fixes trac #952: Haskell requires consistent overflow behaviour, which
gcc doesn't give without this flag.

Basic -fvia-C code generation is there, not much testing.

Apparently, the original fix never really worked due to typos and oversights.

Add GhcRtsWithPapi=YES to mk/build.mk to turn it on

On recent GNU ELF systems one can mark an object file as not
requiring an executable stack. If all objects- linked into a
program have this note then the program will not use an executable
stack, which is good for security (and some distros have it as a
QA policy). GHC generated code does not need an executable stack
so add the note to the assembly output of the native code
generator (conditional on a configure test).

Consistently used spaces rather than tabs.
Removed trailing whitespace.
Wrapped comments to fit in a standard terminal.

Happy, Alex and Haddock are built separately using Cabal now.

Most of the other users of the fptools build system have migrated to
Cabal, and with the move to darcs we can now flatten the source tree
without losing history, so here goes.

The main change is that the ghc/ subdir is gone, and most of what it
contained is now at the top level.  The build system now makes no
pretense at being multi-project, it is just the GHC build system.

No doubt this will break many things, and there will be a period of
instability while we fix the dependencies.  A straightforward build
should work, but I haven't yet fixed binary/source distributions.
Changes to the Building Guide will follow, too.
