If I remember correctly it's only a Windows problem.

It's been reported before. The VisualC++ tools like spewing into stderr silly 
things like program banners.

Probably, but shouldn't be hard to account for that output as the input they 
pay attention to is minimal. And hopefully we'll be removing that 
post-processing step.

Do you have a solution?? (I don't even know what the problem is ;-) -- If you 
have a common error and solution posting it here is _very_ likely to make us 
add it to the documentation.

I'll likely be the one doing that as it's the compiler I use on Windows. But 
contributions are welcome.
