Problems with rewinddir() on RTEMS

Hi,
on some platforms RTEMS uses a 64-bit type for off_t (in particular PowerPC).
The function rewinddir() is implemented (libc/posix/rewinddir.c) in terms of:
_seekdir((dirp), (off_t)0);
For _seekdir() no prototype is present. GCC chooses to pass (off_t) 0 as a
64-bit parameter (on PowerPC r5 and r6). On the other hand we have
(libc/posix/telldir.c):
void
_DEFUN(_seekdir, (dirp, loc),
register DIR *dirp _AND
long loc)
Which has a different signature compared to above (on PowerPC r4 will contain
loc). We must declare _seekdir() somewhere.
Have a nice day!
