cbindgen-expand-dep-bug

This is a minimal example for reproducing Bug #384.

If you run cargo build, then the bindings.h will look like this:

/* Generated with cbindgen:0.9.0 */

#include <stdarg.h>
#include <stdbool.h>
#include <stdint.h>
#include <stdlib.h>

uint32_t get_x(const dep_struct *dep_struct);

It is missing the dep_struct type definition:

typedef struct {
  uint32_t x;
  double y;
} dep_struct;

That is there, when you comment out the macro expansion in the cbindgen.toml:

[parse.expand]
crates = ["cbindgen-dep"]

This code is based on the minimal example created for mozilla/cbindgen#292, thanks @acfoltzer.
