--wrap-static-fns prints float complex instead of float _Complex

Input C/C++ Header

static int take(float _Complex a, int t) { return (int)__real__(a) + t; }

Bindgen Invocation

$ bindgen input.h --wrap-static-fns --wrap-static-fns-path wrap -- -x c -std=gnu11

Actual Results

bindgen exits 0. The wrapper is:

#include "input.h"

int take__extern(float complex a, int t) { return take(a, t); }

complex is a <complex.h> macro, not a C11 keyword. The header does not include that. clang parses float complex a as a parameter named complex of type float:

wrap.c:5:32: error: expected ')'
int take__extern(float complex a, int t) { return take(a, t); }
                               ^

codegen/serialize.rs writes "float complex" for TypeKind::Complex. The C11 spelling is _Complex / float _Complex.

This is not #3255 (by-value _Complex ABI) or #3468 (integer _Complex panic).

Expected Results

Print float _Complex (or include <complex.h> if you really want float complex) so the wrapper is valid C.

Environment

bindgen: 0.73.1 (rust-lang/rust-bindgen 77cbc723)
clang/libclang: Homebrew clang 21.1.8
rustc: 1.97.1
target: aarch64-apple-darwin
OS: macOS

Start in codegen/serialize.rs, where TypeKind::Complex is serialized, and reproduce the issue with the bindgen invocation shown. Update the C spelling so the generated wrapper uses valid _Complex syntax, then verify that the wrapper compiles without requiring complex.h.
