## AI overview

ReactOS developers added initial RBuild detection for the VC++ compiler, but successful MSVC builds still require code and linker work. The newsletter also reports new kernel-mode driver tests that exposed incorrect DRIVER_OBJECT flags.

## Source excerpt

RBuild and MSVC Getting ReactOS built using Microsoft's compilers has been on the wishlist of several ReactOS developers, but no one really wanted to deal with the monstrosity that RBuild had transformed into. KJK::Hyperion decided his sanity was sufficient enough to survive the experience and has been working for quite some time to get it to be able to use a compiler that is not GCC. So far, his additions allow RBuild to detect the presence of the VC++ compiler, whether you got it through Visual Studio, one of the SDKs, or the WDK.
