HKEY_* and Reg* names once, rather than having near-duplicate code
in the two import attempts.

Also dropped the leading underscore on all the imported symbols,
as it's not appropriate (they're not local to this module).

    The Setup.in entry is sort of a lie; it links with -lexpat, but
    Expat's Makefile doesn't actually build a libexpat.a.  I'll send
    Expat's author a patch to do that; if he doesn't accept it, this
    rule will have to list Expat's object files (ick!), or have a
    comment explaining how to build a .a file.

Kuchling.

NOTE: THIS IS VERY ROUGH ALPHA CODE!

option to disable this (by default, it's false and we clean up).

we still have to *run* the sub-command that creates a built distribution.

multiple built distributions in one run -- it seemed a bit dodgy and I'd
rather remove it than try to beat it into submission right now.

Added 'ztar', 'tar' to 'format_command' dictionary.

eg. sunos5, linux2, irix5.

now done in the 'build_ext' command.

  * build to "Debug" or "Release" temp directory
  * put linker turds (.lib and .exp files) in the build temp directory
  * tack on "_d" to extensions built with debugging
  * added 'get_ext_libname()' help in putting linker turds to temp dir
Also, moved the code that simplifies None to empty list for a bunch
  of options to 'finalize_options()' instead of 'run()'.

specific to building Python extensions.

None in an argument list *terminates* the argument list: further
arguments are *ignored*.  This isn't kosher, but too much code relies
on it, implicitly.  For example, IDLE was pretty broken.

installs Tcl/Tk.

Simplified 'Command.get_peer_option()' a tad -- just call 'find_peer()'
  to get the peer command object.
Updated 'Command.copy_file()' to take a 'link' parameter, just like
  'util.copy_file()' does now.
Added 'Command.make_archive()' to wrap 'util.make_archive()'.

Changes to 'copy_file()':
  * added support for making hard links and symlinks
  * noted that it silently clobbers existing files when copying, but
    blows up if destination exists when linking -- hmmm...
  * error message tweak
Added 'base_name' parameter to 'make_tarball()' and 'make_zipfile()'.
Added 'make_archive()' -- wrapper around 'make_tarball()' or
  'make_zipfile()' to take care of the archive "root directory".

the command that actually creates "dumb" binary distributions, ie.
tarballs and zip files that you just unpack under <prefix> or <exec-prefix>.
Very limited, but it's a start.

Initial revision is pretty limited; it only knows how to generate "dumb"
binary distributions, i.e. a tarball on Unix and a zip file on Windows.
Also, due to limitations in the installation code, it only knows how to
distribute Python library code.  But hey, it's a start.
