Can't build in Win7/64 bit

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set up a working command line environment for VS 2008. (environment vars
include INCLUDE, LIB and PATH. Requires the Windows Platform SDK as well.)
2. check out the tree and run `python setup.py install`
3. Output follows, with DISTUTILS_DEBUG set.

What is the expected output? What do you see instead?
I copied the important lines right here; after them is the verbose output.

What version of the product are you using? On what operating system?
svn revision 48

Please provide any additional information below.

I tried screwing with the linker flags. The problem is
/EXPORT:initpyreplib\_unpack - I haven't done any serious C/C++ linking
work, but I can't figure out why there's a "initpyreplib\" in the symbol
name, and I can't find a symbol called _unpack in the source anywhere.

When I change that flag to /EXPORT:init_unpack it installs, but Python
can't import the module; here's the output, verbose again:

>>> from pyreplib import replay, utils
# C:\Python26\lib\encodings\cp437.pyc matches

After a good night's rest (and messing around with command line options for a 
while),
I managed to compile it manually like so:

cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -IC:\Python26\include 
-IC:\Python26\PC
/Tcsrc\pyunpack.c /Fobuild\temp.win32-2.6\Release\src\pyunpack.obj

cl.exe /c /nologo /Ox /MD /W3 /GS- /DNDEBUG -IC:\Python26\include 
-IC:\Python26\PC
/Tcsrc\unpack.c /Fobuild\temp.win32-2.6\Release\src\unpack.obj

link.exe /DLL /nologo /INCREMENTAL:NO /LIBPATH:C:\Python26\libs
/LIBPATH:C:\Python26\PCbuild /EXPORT:init_unpack
build\temp.win32-2.6\Release\src\pyunpack.obj
build\temp.win32-2.6\Release\src\unpack.obj
/OUT:build\lib.win32-2.6\pyreplib\_unpack.pyd
/IMPLIB:build\temp.win32-2.6\Release\src\_unpack.lib
/MANIFESTFILE:build\temp.win32-2.6\Release\src\_unpack.pyd.manifest

I've attached the built package, in case this doesn't get resolved and other 
Windows
users with less patience for linker errors can make use of it. ;)
