[1.18.0] rewinddir operation

[Xavier Guérin <xavier dot guerin at imag dot fr>]

Dear list,

I just encountered a small issue with rewinddir. Although opendir and readdir works properly
on my operating system, I can't make rewinddir working.
After reading the code of _seekdir, I don't seem to understand how it could work anyway.

It looks like _seekdir relies on dd_hash to locate the the entry the user is looking for.
However, dd_hash is only used by telldir and seekdir. I know that seekdir should only be used
with values returned by telldir, but rewinddir bypasses this restriction and uses 0 as off_t parameter.

Consequently, the first few lines of _seekdir fail, since dd_hash[LOCHASH(0)] does not contain a vaild
ddloc entry.

Could you please tell me what I am missing ?

Thanks in advance,
Xavier
