Integrating C++ header units into Office using MSVC (2/n)

Reading about some internals of Office is always interesting! Kudos to MS devs that are improving constantely the product (or at least they try!)

One thing that I remember about MS was most of people saying "ahh MS is not making good software anymore", however I notice that they are making some progress

> As a side note: it is always better to rely on standard C++ features to prevent repeated file content inclusion

NO it is not. For fucksake, pragma once is better than header guards in 99% of cases, just don't use a rats nest of symbolic links.
