you're most welcome.

if you want me to do something more about that, please say so.  i am not 
motivated to do that for ourselves, but it would be pleasure to help you.

if you are interested, the compiler i use is freely available from 
microsoft at http://msdn.microsoft.com/visualc/vctoolkit2003/.  python24 
(but not python23) distutils also require microsoft .NET Framework SDK 
 
(http://www.microsoft.com/downloads/details.aspx?familyid=9b3a2ca6-3647-4070-9f41-a333c6b9181d&displaylang=en) 
and platform sdk may be needed too 
(http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm).

to make distutils work, i've manually added required registry entries 
pointing at msvc bin, include and lib directories:

=== cut ===
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.1]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.1\VC]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.1\VC\VC_OBJECTS_PLATFORM_INFO]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.1\VC\VC_OBJECTS_PLATFORM_INFO\Win32]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\7.1\VC\VC_OBJECTS_PLATFORM_INFO\Win32\Directories]
"Include Dirs"="E:\\usr\\vc7\\psdk\\include;E:\\usr\\vc7\\include"
"Library Dirs"="E:\\usr\\vc7\\psdk\\lib;E:\\usr\\vc7\\lib"
"Path Dirs"="E:\\usr\\vc7\\bin"
=== cut ===

best wishes,
