Good luck ;-) (when I tried, I gave up before writing anything)

I think you're not using it correctly:

I beleive this should be lower_case_cprefix. And

cprefix works on name spaces, not individual symbols. you should set
it in the class to have it apply to its methods/inner classes (but I
think lower_case_cprefix should be used for methods)

There is no such thing as a [Compact] struct ;-p (I understand you
have just forgot it)
> [CCode (cname ="xmlrpc_env", cprefix="xmlrpc_env_", free_function="",

no need for a free function, and I think it should be
destroy_function="xmlrpc_env_clean"
> public struct Env {
> [...]

This could be simply the constructor (it's a struct).
> [CCode (cname ="xmlrpc_value", cprefix="xmlrpc_value_",
> free_function="")]
> public class Value {
I belive it should be ref_function="xmlrpc_INCREF",
unref_function="xmlrpc_DECREF"
btw, cprefix is not needed here

Why not? I don't see the problem.

I'm not sure what's the best way is, but something I'd like to have in
this "abstraction" is throwing errors (constantly checking for
env.fault_occured isn't nice) but I'm afraid you would end up with a
wrapper library rather than a vapi file :-/
HTH, (read : I hope my incoherent rambling makes sense to you)
