Building with MSVC
Building the kernel with MSVC 9.0 (codename Orcas)
1. "make msvc9" on a tree, this will result in a project files being created automatically, and a big ReactOS_auto.sln solution file with ALL projects there. Beware, it's huge!
2. Open up the solution in the MSVC, change Configuration to "Release" or "Debug" (but not the one with "ReactOS Headers").
