Fix paths to HsStd.h.

Fix typo.

For GHCen < 5.00, assume that Exception.throwTo is Exception.raiseInThread

Forced commit to note that the previous commit also adds flushing of
stdout/stderr before printing an exception.  This fixes the problem
reported by Leon Smith last week.

Fix Unix imports

Adapted to changes in build system

Make it compile

More windows wibbles

* Restore SysTools.system, which implements a kludged version
  of system for reasons that are explained at length in the comments
  [overlong command-lines fail if compiling GHC with pre-5.02 GHCs]

* Wibble in Makefile

Restore an #ifdef mingw32_TARGET_OS that shouldn't have been removed
(but do it better this time and don't use an arch-specific #ifdef).

- separate location installed binaries from non-binaries (previously
  installed package.conf was in $(libdir)/extra-bin).

- remove v_Path_Perl so that we don't accidentally wire-in the location of
  perl on Unix systems.  It wasn't actually used anywhere.

- minor non-functional cleanups and comment fixups.

- We still look for package.conf twice; I haven't done anything about
  this yet.

import Packages

override $(libexecdir) to be $(libdir)/bin (the installation machinery
will have to catch up with this too).

Some tidying up

* Remove CmStaticInfo
   - GhciMode moves to HscTypes
   - The package stuff moves to new module main/Packages.lhs

[put any package-related stuff in the new module]

* Add Outputable.docToSDoc

Add getExecDir to return current directory of executable on Windows (to find
config information).

Windows wibbles

- CURRENT_DIR isn't used any more
- TmpFiles doesn't exist

fix typo in Simon's commit (cGHC_RAWCPP ==> GHC_RAWCPP)

----------------------
	Installation packaging
	----------------------

GHC runs various system programs like
	cp, touch
	gcc, as, ld etc

On Windows we plan to deliver these programs along with GHC,
so we have to be careful about where to find them.

This commit isolates all these dependencies in a single module

	main/SysTools.lhs

Most of the #ifdefery for mingw has moved into this module.
There's some documentation in SysTools.lhs

Along the way I did lots of other cleanups.  In particular

  * There is no more 'globbing' needed when calling runSomething
  * All file removal goes via the standard Directory.removeFile
  * TmpFiles.hs has gone; absorbed into SysTools
  * Some DynFlag stuff has moved from DriverFlags to CmdLineOpts


Still to do:

  **	I'm a bit concerned that calling removeFile one at a time
	when deleting masses of split-object files is going to be
	rather slow

  **	GHC now expects to find split,mangle,unlit in
		libdir/extra-bin
	instead of just
		libdir

	So something needs to change in the Unix installation scripts

  **    The "ineffective C preprocessor" is a perversion and should die

just move some code around.

comment fixes

Make some paths work.

Remove redundant and wrong ILX lines.

Remove confusing out-of-date comment.

Add an ext_name string to foreign dotnet types.

Stop using kludgedSystem; the new Windows implementation of system works
instead.

correct a comment (the -B option is mandatory).

re-do package path munging that I b?rked yesterday

Reimplement system() properly on Windows. This avoids two problems with
Windows system(): first, the maximum command-line length, and secondly, the
fact that system() returns before the command has completed, and sleep() was
used to hack around this.

This doesn't affect the use of kludgedSystem, which needs to be removed for
GHC not to need a shell at all.

good riddance

Don't install the pkgconf binary in a BIN_DIST any more.

Allow paths in package.conf to begin with the string "$libdir" which
is magically replaced by the compiler with either

  (a) the argument to the -B<dir> option, if one is present, or
  (b) the wired-in libdir otherwise.

This means that the standard package.conf file is independent of the
install location and we don't need the post-install-script hack any
more (Julian - could you update the install machinery when the time
comes? thanks.)

Make CoreTidy clone all top-level names

Ensure the boilerplate rule still applies for building HSstd_cbits.o.

document data types with no constructors

Changes to build HSstd1.o and HSstd2.o for GHCi in lib/std

	Tidy up and improve "pattern contexts"
	--------------------------------------

In various places (renamer, typechecker, desugarer) we need to know
what the context of a pattern match is (case expression, function defn,
let binding, etc).  This commit tidies up the story quite a bit.  I
think it represents a net decrease in code, and certainly it improves the
error messages from:

	f x x = 3

Prevsiously we got a message like "Conflicting bindings for x in a pattern match",
but not it says "..in a defn of function f".

WARNING: the tidy up had a more global effect than I originally expected,
so it's possible that some other error messages look a bit peculiar.  They
should be easy to fix, but tell us!
