Any suggestions? Code and artwork/assets are all in SVN, and we don't want to port it to GCC or another compiler before anyone suggests it! Simplicity and minimising 3rd-party tools is preferred, since we don't have a build-server it'll probably still be run on a developer's PC but we don't want them just doing a build manually and packaging it up.
It's basically just a C++ solution with several projects, plus we have an Inno Setup installer to build.
Right now it's a 3-step process (or 4 if you include uploading the release to FTP):
You can use MSVC pre, post & custom build steps to do this, they run programs through the windows command line. also see this: http://blogs.msdn.com/b/visualstudio/archive/2010/04/26/custom-build-steps-tools-and-events.aspx
