The problem is that every MSVC has its own libc / CRT (msvcrt.dll) with
its own implementations of malloc(), FILE pointer, thread local storage,
errno etc. You shouldn't mix multiple CRTs in one program as this may
lead to crashes and hard to find bugs.

Why do you want to compile your own Keccak / SHA-3 binaries anyway? I
have build and released binaries for X86 and X86_64 Windows and for
Python 2.6 and 3.3. For Python 3.4 I'm working on a PEP about the
integration of pbkdf2, bcrypt and scrypt into Python's stdlib.
