Function in C file not generated if a typedef added in header file.

[jamesrr39]

Hi,

It appears a function that is defined in C code is not generated if it is defined after an enum type definition. An example to reproduce:

src/a.h

typedef enum {
    FIRST = 0
} X;

int a();

src/a.c

#include "a.h"

int a() {
    return 1;
}

cxgo.yml

root: ./src
out: ./out
package: out
use_go_int: true
files:
  - name: '*'

What is generated:
out/a.go

package out

type X int

const FIRST X = 0

(a() function is not in generated Go code)
