I have the feeling that will apply to most alternatives. The problem
is to turn the C code into machine code, right? That is a difficult
problem, which is why a C compiler is a complex piece of software.
Using a different tool is not going to turn it into a simple problem.

So I think gcc is still the best bet. If the issue with the return
point is the only problem, there should be several possible solution
(with different performance impact).
