As Chris indicated, the code that you quoted from the .i file earlier in
the thread is definitely C++11 code, which VS2005 cannot compile, which
in turn is probably why you're getting the errors.
Hence something you are including contains the wrong code. Either you
are including a C++11-only library somewhere, your include paths are
wrong (and eg. including CRT code from the wrong version of VS), or
you're defining preprocessor symbols that you shouldn't and hence
confusing Boost's platform detection.
On that note, what do you have in the C++/Preprocessor/Preprocessor
Definitions setting? (Click on it and go to Edit, then copy both the
top panel and the bottom Inherited Values panel.)

You need to turn the option off again after generating the .i file, just
like the option to generate the .i file in the first place.

These sorts of errors suggest that you probably didn't turn off
precompiled headers. You need to do that when compiling a .i file,
since it contains all the code inline instead of including the stdafx.h
