YACoind. now compiles on  MSVC++ 2005 and later

No meaningful changes have been made to the gcc sources, though some of
the MSC changes may be of interest.
This is only for VS 2005

I forgot this one file, that presumes a VS 2008 or later.  In 2005, MS
didn't have a "tmmintrin.h" file for SSSE3 instructions.

assertions, assertions

I kept the side affects of all the assertions in so release mode would
behave like debug mode.

Also changed the method by which YACoind exits in MS so it is a little
more "correct".
