Issue5407

Broken Py3.1 release build in Visual Studio 2005

The CRT runtime structure that holds ioinfo doesn't appear to match the decleration from the headers provided with the Visual Studio 2005 crt sources.  In Release, an extra 8 bytes follow the final BOOL.  I cannot explain this, but the code works now, both in 32 bits and 64
