There are a lot of companies still using VS C++ 6.0, and alot don't want to upgrade.

I think the point was not that the book was aimed at an older compiler, but that it was aimed specificly at Microsoft's compilers. This means that at least some of the tricks in the book wouldn't work in other compilers, such as GCC, CodeWarrior, etc., and the only compiler they would work in is Windows only. So the tricks are useless in portable code.
