   Why? This approach simplifies having one frontend and multiple backends.
- Use C as an intermediate language to feed a backend (any C compiler can act as the backend).
   The backend can then focus solely on code generation.

Presumably this translator will only target 32-bit systems even if run on a 64-bit one?

 It will have to be configured to x86 or x64. It has to match the target/ platform compiler settings. The online versions is emulating something. I think x86 gcc on linux.

Obs:
The platform windows\linux makes difference in the size of wchar_t L'a' also on sizes of long etc.. In practice the result is assuming fixed sizes. I may add at the end of generated code the assumptions . It can be in a static_assert form.
