Right. So my argument about GNU cpp was not valid, since, in principle
at least, there are non-GPL alternatives.

How does that work in practice? What are people using on e.g. Windows as
GHC's C-backend to avoid GPL? I venture that the native (Microsoft's) C
compiler does not enter the picture here, it does not even support C90.
Perhaps they use the LLVM backend?
