distutils/command/bdist_wininst.py:
- the windows installer is again able to compile after installing
  the files. Note: The default has changed, the packager has to
  give --no-target-compile/--no-target-optimize to NOT compile
  on the target system. (Another note: install_lib's --compile
  --optimize options have the same semantics to switch off
  the compilation. Shouldn't the names change?)
- All references to specific python versions are gone.
- A small bug:
    raise DistutilsPlatformError ("...")
  instead of
    raise DistutilsPlatformError, ("...")
- When bdist_wininst creates an installer for one specific python
  version, this is reflected in the name:
    Distutils-0.9.2.win32-py15.exe instead of
    Distutils-0.9.2.win32.exe
- bdist_wininst, when run as script, reads the wininst.exe file
  and rewrites itself. Previously this was done by hand.

- All the changes needed for compilation
- Deleted a lot of debug/dead code
