  Backport of the PCbuild9 directory from the py3k branch.
  I've finished the last task for the PCbuild9 directory today. I don't think there is much left to do. Now you can all play around with the shiny new VS 2008 and try the PGO builds. I was able to get a speed improvement of about 10% on py3k.
  Have fun! :)

  Fixed problems in the last commit. Filenames and line numbers weren't reported correctly.
  Backquotes still don't report the correct file. The AST nodes only contain the line number but not the file name.

  And yet another fix for the patch. Paul Moore has send me a note that I've missed a declaration. The additional code has moved the declaration in the middle of the block.

  Major change in the internal structure of the Decimal
  number: now it does not store the mantissa as a tuple
  of numbers, but as a string.

  This avoids a lot of conversions, and achieves a
  speedup of 40%. The API remains intact.

  Thanks Mark Dickinson.

  Added filename to compiling struct based on Martin's suggestion.
  I'm wonder why I was trying to add the filename to the node all the time. The compiling struct is more obvious.
