relax SVN archive

Windows scons C module compilation now defaults to 32-bit.

This is because the default Python downloads are 32-bit. And many libraries (e.g. numpy and scipy)
are only pre-compiled as 32-bit. Hence a 64-bit relax build on Windows will require a lot of custom
compilation that most users will never do.
