fairly tight control, and the '_setup_stop_after' and '_setup_distribution'
globals to provide the tight control.

This isn't entirely reliable yet: it dies horribly with a NameError on the
example PIL setup script in examples/pil_setup.py (at least with Python
1.5.2; untested with current Python).  There's some strangeness going
on with execfile(), but I don't understand it and don't have time
to track it down right now.

according to the MS docs it enables exception-handling, and (according
to Alex Martelli <aleaxit@yahoo.com>) is needed to compile without
getting warnings from standard C++ library headers.  Apparently
it doesn't cause any problems with C code, so I haven't bothered
conditionalizing the use of /GX.

Changed 'core.setup()' so it sets them to reasonable defaults.
Tweaked how the "usage" string is generated: 'core' now provides
  'gen_usage()', which is used instead of 'USAGE'.
Modified "build_py" and "sdist" commands to refer to
  'self.distribution.script_name' rather than 'sys.argv[0]'.

Fix bad operator precedence: should be "(metadata or '') + '\n'".

The known bug (bogus error message when an empty file is
extracted) is fixed.

Other changes:

- The target-compile and target-optimize flags of bdist_wininst
  are gone. It is no longer possible to compile the python
  files during installation.
- The zlib module is no longer required or used by bdist_wininst.

- I moved the decompression/extraction code into a separate
  file (extract.c).

- The installer stub is now compressed by UPX (see
  http://upx.tsx.org/). This reduces the size of the exe
  (and thus the overhead of the final installer program)
  from 40 kB to 16 kB.

- The installer displays a more uptodate user wizard-like
  user interface, also containing a graphic: Just's Python Powered logo.
  (I could not convince myself to use one of the BeOpen logos).
- The installation progress bar now moves correctly.

in 'get_package_dir()', too -- can now assume that 'package' is a string.

  * use self.debug_print() for debug messages
  * uses now copy.copy() to copy lists
  * added 'shared_lib_extension=".dll"', ... , this is necessary if you
    want use the compiler class outside of the standard distutils build
    process.
  * changed result type of check_config_h() from int to string

  * changed some list.extend([...]) to list.append(...)
  * added '/g0' to compiler_options, so compiler doesn't
    stop after 100 warnings

hacked on at the very last minute (essential if the .pth file is to be
included in an RPM or other smart installer!).

consistency.

  - added big comment describing possible problems
  - look for and react to versions of gcc, ld, and dlltool; mainly
    this is done by the 'get_versions()' function and the CygwinCCompiler
    and Mingw32CCompiler constructors
  - move 'check_config_h()' to end of file and defer calling it until
    we need to (ie. in the CygwinCCompiler constructor)
  - lots of changes in 'link_shared_object()' -- mostly seems to be
    library and DLL stuff, but I don't follow it entirely
