Thank you Jerome and all the people that have answered me, I was ignorant about GNU license.

If someone writes a compiler/language that allows programs to be ported with no problems from Windows to other nonwindows systems, this may damage Windows a little (but isn't Mono able to do this with C#2 programs?).

But it's economically advantageous for Microsoft to make it easy for people to create new compilers and languages for Windows that work well with other Windows programs. So in my opinion having a good Clang++ on Windows is good for the economic well-being of Windows. They can grant LLVM a free licence to use Windows-style exceptions.
