--- Comment #2 from Hannes Domani <ssbssa at sourceware dot org> ---
The reason is, gnulib/config.h has this define:

```
/* For 64-bit time_t on 32-bit mingw. */
#define __MINGW_USE_VC2005_COMPAT 1
```

And bfd doesn't do this, so you get different definitions of struct stat.

In bfd/bfdio.c:

```
(top-gdb) pt buf
type =3D struct _stati64 {
    _dev_t st_dev;
    _ino_t st_ino;
    unsigned short st_mode;
    short st_nlink;
    short st_uid;
    short st_gid;
    _dev_t st_rdev;
    long long st_size;
    __time32_t st_atime;
    __time32_t st_mtime;
    __time32_t st_ctime;
}
```

And in gdb/symfile.c:

```
(top-gdb) pt new_statbuf
type =3D struct _stat64 {
    _dev_t st_dev;
    _ino_t st_ino;
    unsigned short st_mode;
    short st_nlink;
    short st_uid;
    short st_gid;
    _dev_t st_rdev;
    long long st_size;
    __time64_t st_atime;
    __time64_t st_mtime;
    __time64_t st_ctime;
}
```
