I think that's a mistake, Chris. The only place Boost includes headers
with the same names as standard ones is in the compatibility
library. If we are replacing any standard headers, it's intentional. I
think the reason you have trouble with CW is their crazy convention of
automatically enabling *recursive* search through any of the #include
paths you specify. IMO you should turn that off and specify each
directory explicitly, so you know what you're getting.
