IIRC, Leor Zolman's stlfilt used to provide a drop-in replacement for cl.exe. However, that behaved exactly like cl.exe did. I have seen threads referring to replacing the native cl.exe with one of a different compiler version, and it seems even that could be problematic.

The Windows version of Intel's compiler plugs into VS, though, and that's EDG-based, so you might try that. However, I don't think that's free on Windows.

You should be able to alter your .vcproj files to specify a different MSBuild task instead of cl.exe. You can find more information about this on the MSDN website, but it's perfectly possible to launch a third party tool.

Give more details maybe? I'd like to hear a bit more on that.

@Poni: I don't really know that much about it - failed to make anything happen on my own. You'll have to check MSDN.
