Interestingly, I recently auto-translated wget from C to a memory-safe subset of C++ [1], which involves the intermediate step of auto-converting from C to the subset of C that will also compile under clang++. You end up with a bunch of clang++ warnings about various things being C11 extensions and not ISO C++ compliant, but it does compile.
