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! :)

+Building Python using VC++ 9.0
+------------------------------
+This directory is used to build Python for Win32 platforms, e.g. Windows
+2000, XP and Vista.  It requires Microsoft Visual C++ 9.0
+(a.k.a. Visual Studio .NET 2008).
+(For other Windows platforms and compilers, see ../PC/readme.txt.)
+
+All you need to do is open the workspace "pcbuild.sln" in MSVC++, select
+the Debug or Release setting (using "Solution Configuration" from
+the "Standard" toolbar"), and build the projects.
+
+The proper order to build subprojects:
+
+1) pythoncore (this builds the main Python DLL and library files,
+               python30.{dll, lib} in Release mode)
+
+2) python (this builds the main Python executable,
+           python.exe in Release mode)
+
+3) the other subprojects, as desired or needed (note:  you probably don't
+   want to build most of the other subprojects, unless you're building an
+   entire Python distribution from scratch, or specifically making changes
+   to the subsystems they implement, or are running a Python core buildbot
+   test slave; see SUBPROJECTS below)
+
+When using the Debug setting, the output files have a _d added to
+their name:  python30_d.dll, python_d.exe, parser_d.pyd, and so on.
+
+SUBPROJECTS
+-----------
+These subprojects should build out of the box.  Subprojects other than the
+main ones (pythoncore, python, pythonw) generally build a DLL (renamed to
+.pyd) from a specific module so that users don't have to load the code
+supporting that module unless they import the module.
+
+pythoncore
+    .dll and .lib
+python
+    .exe
+pythonw
+    pythonw.exe, a variant of python.exe that doesn't pop up a DOS box
+_socket
+    socketmodule.c
+_testcapi
+    tests of the Python C API, run via Lib/test/test_capi.py, and
+    implemented by module Modules/_testcapimodule.c
+pyexpat
+    Python wrapper for accelerated XML parsing, which incorporates stable
+    code from the Expat project:  http://sourceforge.net/projects/expat/
+select
+    selectmodule.c
+unicodedata
+    large tables of Unicode data
+winsound
+    play sounds (typically .wav files) under Windows
+
+The following subprojects will generally NOT build out of the box.  They
+wrap code Python doesn't control, and you'll need to download the base
+packages first and unpack them into siblings of PCbuilds's parent
+directory; for example, if your PCbuild is  .......\dist\src\PCbuild\,
+unpack into new subdirectories of dist\.
+
+_tkinter
+    Python wrapper for the Tk windowing system.  Requires building
+    Tcl/Tk first.  Following are instructions for Tcl/Tk 8.4.12.
+
+    Get source
+    ----------
+    In the dist directory, run
+    svn export http://svn.python.org/projects/external/tcl8.4.12
+    svn export http://svn.python.org/projects/external/tk8.4.12
+    svn export http://svn.python.org/projects/external/tix-8.4.0
+
+    Build Tcl first (done here w/ MSVC 7.1 on Windows XP)
+    ---------------
+    Use "Start -> All Programs -> Microsoft Visual Studio .NET 2003
+         -> Visual Studio .NET Tools -> Visual Studio .NET 2003 Command Prompt"
+    to get a shell window with the correct environment settings
+    cd dist\tcl8.4.12\win
+    nmake -f makefile.vc
+    nmake -f makefile.vc INSTALLDIR=..\..\tcltk install
+
+    XXX Should we compile with OPTS=threads?
+
+    Optional:  run tests, via
+        nmake -f makefile.vc test
+
+        On WinXP Pro, wholly up to date as of 30-Aug-2004:

+        Sourced 129 Test Files.
+
+    Build Tk
+    --------

+    nmake -f makefile.vc TCLDIR=..\..\tcl8.4.12
+    nmake -f makefile.vc TCLDIR=..\..\tcl8.4.12 INSTALLDIR=..\..\tcltk install
+
+    XXX Should we compile with OPTS=threads?
+
+    XXX Our installer copies a lot of stuff out of the Tcl/Tk install
+    XXX directory.  Is all of that really needed for Python use of Tcl/Tk?
+
+    Optional:  run tests, via
+        nmake -f makefile.vc TCLDIR=..\..\tcl8.4.12 test
+
+        On WinXP Pro, wholly up to date as of 30-Aug-2004:

+   cd dist\tix-8.4.0\win
+   nmake -f python.mak
+   nmake -f python.mak install
+
+bz2
+    Python wrapper for the libbz2 compression library.  Homepage
+        http://sources.redhat.com/bzip2/
+    Download the source from the python.org copy into the dist
+    directory:
+
+    svn export http://svn.python.org/projects/external/bzip2-1.0.3
+
+    A custom pre-link step in the bz2 project settings should manage to
+    build bzip2-1.0.3\libbz2.lib by magic before bz2.pyd (or bz2_d.pyd) is
+    linked in PCbuild\.
+    However, the bz2 project is not smart enough to remove anything under
+    bzip2-1.0.3\ when you do a clean, so if you want to rebuild bzip2.lib
+    you need to clean up bzip2-1.0.3\ by hand.
+
+    The build step shouldn't yield any warnings or errors, and should end
+    by displaying 6 blocks each terminated with
+        FC: no differences encountered
+
+    All of this managed to build bzip2-1.0.3\libbz2.lib, which the Python
+    project links in.
+
+
+_bsddb
+    To use the version of bsddb that Python is built with by default, invoke
+    (in the dist directory)
+
+     svn export http://svn.python.org/projects/external/db-4.4.20
+
+
+    Then open a VS.NET 2003 shell, and invoke:
+
+       devenv db-4.4.20\build_win32\Berkeley_DB.sln /build Release /project db_static
+
+    and do that a second time for a Debug build too:
+
+       devenv db-4.4.20\build_win32\Berkeley_DB.sln /build Debug /project db_static
+
+    Alternatively, if you want to start with the original sources,
+    go to Sleepycat's download page:
+        http://www.sleepycat.com/downloads/releasehistorybdb.html
+
+    and download version 4.4.20.
+
+    With or without strong cryptography? You can choose either with or
+    without strong cryptography, as per the instructions below.  By
+    default, Python is built and distributed WITHOUT strong crypto.
+
+    Unpack the sources; if you downloaded the non-crypto version, rename
+    the directory from db-4.4.20.NC to db-4.4.20.
+
+    Now apply any patches that apply to your version.
+
+    Open
+        dist\db-4.4.20\docs\index.html
+
+    and follow the "Windows->Building Berkeley DB with Visual C++ .NET"
+    instructions for building the Sleepycat
+    software.  Note that Berkeley_DB.dsw is in the build_win32 subdirectory.
+    Build the "db_static" project, for "Release" mode.
+
+    To run extensive tests, pass "-u bsddb" to regrtest.py.  test_bsddb3.py
+    is then enabled.  Running in verbose mode may be helpful.
+
+    XXX The test_bsddb3 tests don't always pass, on Windows (according to
+    XXX me) or on Linux (according to Barry).  (I had much better luck
+    XXX on Win2K than on Win98SE.)  The common failure mode across platforms
+    XXX is
+    XXX     DBAgainError: (11, 'Resource temporarily unavailable -- unable
+    XXX                         to join the environment')
+    XXX
+    XXX and it appears timing-dependent.  On Win2K I also saw this once:
+    XXX
+    XXX test02_SimpleLocks (bsddb.test.test_thread.HashSimpleThreaded) ...
+    XXX Exception in thread reader 1:

+    XXX
+    XXX I'm told that DBLockDeadlockError is expected at times.  It

+
+    Building for Win64:
+    - open a VS.NET 2003 command prompt
+    - run the SDK setenv.cmd script, passing /RETAIL and the target
+      architecture (/SRV64 for Itanium, /X64 for AMD64)
+    - build BerkeleyDB with the solution configuration matching the
+      target ("Release IA64" for Itanium, "Release AMD64" for AMD64), e.g.
+    devenv db-4.4.20\build_win32\Berkeley_DB.sln /build "Release AMD64" /project db_static /useenv
+
+_sqlite3
+    Python wrapper for SQLite library.
+    
+    Get the source code through
+    
+    svn export http://svn.python.org/projects/external/sqlite-source-3.3.4
+    
+    To use the extension module in a Python build tree, copy sqlite3.dll into
+    the PCbuild folder.
+
+_ssl
+    Python wrapper for the secure sockets library.
+
+    Get the source code through
+
+    svn export http://svn.python.org/projects/external/openssl-0.9.8g
+
+    Alternatively, get the latest version from http://www.openssl.org.
+    You can (theoretically) use any version of OpenSSL you like - the
+    build process will automatically select the latest version.
+
+    You must also install ActivePerl from
+        http://www.activestate.com/Products/ActivePerl/
+    as this is used by the OpenSSL build process.  Complain to them <wink>.
+
+    You also need the NASM assembler
+    from http://www.kernel.org/pub/software/devel/nasm/binaries/win32/
+    Put nasmw.exe anywhere in your PATH.
+
+    The MSVC project simply invokes PCBuild/build_ssl.py to perform
+    the build.  This Python script locates and builds your OpenSSL
+    installation, then invokes a simple makefile to build the final .pyd.
+
+    build_ssl.py attempts to catch the most common errors (such as not
+    being able to find OpenSSL sources, or not being able to find a Perl
+    that works with OpenSSL) and give a reasonable error message.
+    If you have a problem that doesn't seem to be handled correctly
+    (eg, you know you have ActivePerl but we can't find it), please take
+    a peek at build_ssl.py and suggest patches.  Note that build_ssl.py
+    should be able to be run directly from the command-line.
+
+    build_ssl.py/MSVC isn't clever enough to clean OpenSSL - you must do
+    this by hand.
+
+Building for Itanium
+--------------------
+
+The project files support a ReleaseItanium configuration which creates
+Win64/Itanium binaries. For this to work, you need to install the Platform
+SDK, in particular the 64-bit support. This includes an Itanium compiler
+(future releases of the SDK likely include an AMD64 compiler as well).
+In addition, you need the Visual Studio plugin for external C compilers,
+from http://sf.net/projects/vsextcomp. The plugin will wrap cl.exe, to
+locate the proper target compiler, and convert compiler options
+accordingly. The project files require atleast version 0.9.
+
+Building for AMD64
+------------------
+
+The build process for the ReleaseAMD64 configuration is very similar
+to the Itanium configuration; make sure you use the latest version of
+vsextcomp.
+
+Building Python Using the free MS Toolkit Compiler
+--------------------------------------------------
+
+The build process for Visual C++ can be used almost unchanged with the free MS
+Toolkit Compiler. This provides a way of building Python using freely
+available software.
+
+Note that Microsoft have withdrawn the free MS Toolkit Compiler, so this can
+no longer be considered a supported option. The instructions are still
+correct, but you need to already have a copy of the compiler in order to use
+them. Microsoft now supply Visual C++ 2005 Express Edition for free, but this
+is NOT compatible with Visual C++ 7.1 (it uses a different C runtime), and so
+cannot be used to build a version of Python compatible with the standard
+python.org build. If you are interested in using Visual C++ 2005 Express
+Edition, however, you should look at the PCBuild8 directory.
+
+Requirements
+
+    To build Python, the following tools are required:
+
+    * The Visual C++ Toolkit Compiler
+        no longer available for download - see above
+    * A recent Platform SDK
+        from http://www.microsoft.com/downloads/details.aspx?FamilyID=484269e2-3b89-47e3-8eb7-1f2be6d7123a
+    * The .NET 1.1 SDK
+        from http://www.microsoft.com/downloads/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d
+
+    [Does anyone have better URLs for the last 2 of these?]
+
+    The toolkit compiler is needed as it is an optimising compiler (the
+    compiler supplied with the .NET SDK is a non-optimising version). The
+    platform SDK is needed to provide the Windows header files and libraries
+    (the Windows 2003 Server SP1 edition, typical install, is known to work -
+    other configurations or versions are probably fine as well). The .NET 1.1
+    SDK is needed because it contains a version of msvcrt.dll which links to
+    the msvcr71.dll CRT. Note that the .NET 2.0 SDK is NOT acceptable, as it
+    references msvcr80.dll.
+
+    All of the above items should be installed as normal.
+
+    If you intend to build the openssl (needed for the _ssl extension) you
+    will need the C runtime sources installed as part of the platform SDK.
+
+    In addition, you will need Nant, available from
+    http://nant.sourceforge.net. The 0.85 release candidate 3 version is known
+    to work. This is the latest released version at the time of writing. Later
+    "nightly build" versions are known NOT to work - it is not clear at
+    present whether future released versions will work.
+
+Setting up the environment
+
+    Start a platform SDK "build environment window" from the start menu. The
+    "Windows XP 32-bit retail" version is known to work.
+
+    Add the following directories to your PATH:
+        * The toolkit compiler directory
+        * The SDK "Win64" binaries directory
+	* The Nant directory
+    Add to your INCLUDE environment variable:
+        * The toolkit compiler INCLUDE directory
+    Add to your LIB environment variable:
+        * The toolkit compiler LIB directory
+	* The .NET SDK Visual Studio 2003 VC7\lib directory
+
+    The following commands should set things up as you need them:
+
+        rem Set these values according to where you installed the software
+        set TOOLKIT=C:\Program Files\Microsoft Visual C++ Toolkit 2003
+        set SDK=C:\Program Files\Microsoft Platform SDK
+        set NET=C:\Program Files\Microsoft Visual Studio .NET 2003
+        set NANT=C:\Utils\Nant
+
+        set PATH=%TOOLKIT%\bin;%PATH%;%SDK%\Bin\win64;%NANT%\bin
+        set INCLUDE=%TOOLKIT%\include;%INCLUDE%
+        set LIB=%TOOLKIT%\lib;%NET%\VC7\lib;%LIB%
+
+    The "win64" directory from the SDK is added to supply executables such as
+    "cvtres" and "lib", which are not available elsewhere. The versions in the
+    "win64" directory are 32-bit programs, so they are fine to use here.
+
+    That's it. To build Python (the core only, no binary extensions which
+    depend on external libraries) you just need to issue the command
+
+        nant -buildfile:python.build all
+
+    from within the PCBuild directory.
+
+Extension modules
+
+    To build those extension modules which require external libraries
+    (_tkinter, bz2, _bsddb, _sqlite3, _ssl) you can follow the instructions
+    for the Visual Studio build above, with a few minor modifications. These
+    instructions have only been tested using the sources in the Python
+    subversion repository - building from original sources should work, but
+    has not been tested.
+
+    For each extension module you wish to build, you should remove the
+    associated include line from the excludeprojects section of pc.build.
+
+    The changes required are:
+
+    _tkinter
+        The tix makefile (tix-8.4.0\win\makefile.vc) must be modified to
+	remove references to TOOLS32. The relevant lines should be changed to
+	read:
+            cc32 = cl.exe
+            link32 = link.exe
+            include32 = 
+	The remainder of the build instructions will work as given.
+
+    bz2
+        No changes are needed
+
+    _bsddb
+        The file db.build should be copied from the Python PCBuild directory
+	to the directory db-4.4.20\build_win32.
+
+	The file db_static.vcproj in db-4.4.20\build_win32 should be edited to
+	remove the string "$(SolutionDir)" - this occurs in 2 places, only
+	relevant for 64-bit builds. (The edit is required as otherwise, nant
+	wants to read the solution file, which is not in a suitable form).
+
+	The bsddb library can then be build with the command
+	    nant -buildfile:db.build all
+	run from the db-4.4.20\build_win32 directory.
+
+    _sqlite3
+        No changes are needed. However, in order for the tests to succeed, a
+	copy of sqlite3.dll must be downloaded, and placed alongside
+	python.exe.
+
+    _ssl
+        The documented build process works as written. However, it needs a
+	copy of the file setargv.obj, which is not supplied in the platform
+	SDK. However, the sources are available (in the crt source code). To
+	build setargv.obj, proceed as follows:
+
+        Copy setargv.c, cruntime.h and internal.h from %SDK%\src\crt to a
+	temporary directory.
+	Compile using "cl /c /I. /MD /D_CRTBLD setargv.c"
+	Copy the resulting setargv.obj to somewhere on your LIB environment
+	(%SDK%\lib is a reasonable place).
+
+	With setargv.obj in place, the standard build process should work
+	fine.
+
+YOUR OWN EXTENSION DLLs
+-----------------------
+If you want to create your own extension module DLL, there's an example
+with easy-to-follow instructions in ../PC/example/; read the file
+readme.txt there first.
