* Added the MPI version information to the mpi4py information printout.
* 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.
* Added support in the information printout for Windows versions of the '<code>file' </code> program. This enables the C modules to be identified as 32 or 64-bit, if the '<code>file' </code> program is installed.
