<p>Is a cfront tool available for the new C++? For any other modern languages?</p>

What do you mean by “cfront tool”? Cfront was the first C++ compiler. But since failure to add exception support,
it has been discontinued
. Modern C++ is way beyond the scope of Cfront.
For any other modern languages?
And what do you mean by that? If you mean whether other compilers exist that compile a high-level language into C code then the answer is yes, there are plenty. The
Glasgow Haskell Compiler
is just one out of many.
