Drop the dependency on the Win32 library, as it is only used in an
extremely limited way (a single 'foreign import' is all that's reqd)
[Sorry Reuben, I don't buy your 'extra deps are good' argument :-) ]

runSomething: narrow down prev commit, only quote args under mingw;it interacts badly with -D quoting already done on other plats (and isn't reqd)

Add comment and use backslash consistently

1. Make GHC work with paths and filenames containing spaces (hopefully).
This is done by quoting all arguments sent to the shell. To avoid causing
problems, this means that each argument in a list had *better* be a single
argument, hence the next commit to PackageSrc.hs.

2. undosify the path passed as the -h argument to unlit, to make unlit work
on Windows again.

3. Fix getExecDir for Windows (broken by previous changes to the meaning of
-B).

Don't add -I flag for Windows gcc's include files here; do it in
package.conf instead.

Now assume that -B passes libdir, not libexecdir

Fix binary finding for Unix

s/extra-bin/bin/ because this is where all programs are installed to.
Perhaps it should be changed the other way around - I don't know what
this extra-bin was supposed to be.

check TMPDIR (got lost somewhere in the conversion to SysTools)

runSomething: don't export it

Fix spacing bogon.

Rewrite getExecDir to use GetModuleFileName on Windows (thanks, sof),
and switch unDosifyPath's definitions between Windows and Unix so that
it actually does something on Windows.

Rewrite getExecDir with Win32Registry calls. Duh.

Make getExecDir work on Windows by reading the registry

lib/gcc-lib -> gcc-lib

Changes to nuke RAWCPP.

Add notes

The "Warning: deleting non-existent foo" message should only be
printed in verbose mode.

Copy was ignoring its 'purpose' argument

Change the way that IO exceptions are handled and some associated details:

1. In the top-level exception handler, don't treat IO exceptions as a panic,
just print them out and stop.

2. In the slurping routines SysTools.copy and the fake cpp in
DriverPipeline, don't catch IO exceptions, just let them propagate.

Stop copy adding a newline to the end of the copy

Remove debugging statements^Wexpressions

Fix mangling of -B path.

Fix Unix copy (now same as Windows: slow, but working).

clean up remove_suffix:

  - only use it when getExecDir works (i.e. on Windows)
  - therefore, don't require that the build-tree TOPDIR has a
    /ghc/compiler suffix.
  - fix a bug with the installed build, where the binary lives
    in $libdir/bin not $libdir.

ghci-inplace should work again now.

Reimplement copy as a slurp in Haskell to avoid problems with pesky
Windows command-line tools. Grr.

Make stage two getExecDir for Windows work again. Where did it go before?

Keep pgm paths in native format

Import wibbles

Fix so that it compiles on both pre and post 5.00 series compilers.

Remove hacked-in definition of system for mingwin; instead we now just link
against the new version of systemCmd from lib/std/cbits/system.c.

Instead of using the old kludgedSystem on Windows, use the new system. This
makes the use of DOS built-ins such as copy work, which they didn't when the
command was run under sh (as the old kludgedSystem did).

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

- 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.

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).
