Failure to build component containing flags shape

[eduardomourar]

I am using cargo-component from commit 29fea4a.

While trying to build a component that contains a flags shape (example here), the following error is presented (reproduced here):

error[E0433]: failed to resolve: use of undeclared crate or module wit_bindgen

It looks like I might have missed a place where the generated code was assuming wit_bindgen for the runtime path.

I'll get this fixed in upstream wit-bindgen and resolve this issue once we get it patched.

[peterhuene]

This line is the problem. Looks like we should also be reexporting bitflags from cargo_component_bindings as well.

I've put up bytecodealliance/wit-bindgen#645 to address this; once that merges, a small change is required to cargo-component to resolve the issue.
