Some front ends generate trees which cannot be generated by any C program. It might be possible to add some extensions (which would also help to come up with C test cases for bugs which are currently exposed by non-C front ends only), and this might even ease concerns that an ISO C backend might make it possible to use GCC as a library. But I think it's still better to use some binary serialized IL, just to discourage external reuse and make clear that it's an internal format, subject to frequent changes.
