Attempt to reduce the number of compilation errors with MSVC 2005 & 2008

Everything is in the title

WARNING-1: This does not mean, having a working build !!
WARNING-2: Contrary to with VS 10+, for VS 2005/2008 you need to use "ninja -j 1" (i.e. no parallel builds) to build ReactOS, otherwise you end up in concurrent accesses failures to .PDB files (known bug in VS 2005/2008).

EDIT: Doing a ninja (--> parallel) build with MSVC 2008 seems to work, if your bin. output directory is not in a shared folder of a VM...
