That could not work in general, because C has macros (think of the `EOF` 
macro constant in `<stdio.h>`) that have no equivalent in libgccjit. And 
in practice C macros are very important (and a lot of API for C are 
using macros, see also macros such as WIFEXITED in wait(2) on some Linux 
system).

We have to admit that C and libgccjit are different "languages" (even if 
conceptually very close). And a C API is not exactly a set of "objects" 
that libgccjit can handle.
