wrap-static-fns converts _Bool to bool, causing a compile error

I made a little wrapper header using _Bool to avoid having to include stdbool.h since I was being lazy and didn't want to exclude a few symbols. It translated the _Bool to bool in the wrap-static-fns generated wrapper, which caused a compilation failure.

(Workaround: Just use stdbool. It’s not a big deal to filter out the few definitions.)

Input C/C++ Header

static inline _Bool example() { return 1; }

Bindgen Invocation

$ bindgen input.h --experimental --wrap-static-fns --wrap-static-fns-path=wrapper

Actual Results

It generates this wrapper, with _Bool translated to bool.

#include "input.h"

// Static wrappers

bool example__extern(void) { return example(); }

which produces this error:

wrapper.c:5:1: error: unknown type name 'bool'
bool example__extern(void) { return example(); }
^
1 error generated.

Expected Results

The generated wrappers should use _Bool as provided in the input.

Start with the --wrap-static-fns entry point using the provided input.h and bindgen invocation, then inspect how the generated wrapper represents the _Bool return type. Done means the wrapper uses _Bool as expected and wrapper.c compiles without the unknown type name error.
