How is it implemented? No, I'm saying that other windows ports of GNU tools most likely (mis)use ctime as birthtime, whereas cygwin properly uses ctime as ctime and exposes birthtime separately. Since the BLODA is affecting ctime, but only cygwin is exposing ctime, then only cygwin is likely to be affected by this patch. --=20 Eric Blake eblake AT redhat DOT com +1-801-349-2682 Libvirt virtualization library http://libvirt.org --------------enig80A7385758E5ADD4E8DB9A50 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org/ iQEcBAEBCAAGBQJNuYM1AAoJEKeha0olJ0NqxPUH/3GK0Le+1RoNvpcYE33kd4ox +iP3HeVB1rUZ0RW0mjr+6o3jXhqTGUopX8OJ+4MtXp5p6IHf8rnzzjb3/w9oupTh D/xYWQiokPfDu+7Fv7xtFGg+Y5UGCjIg45rlYFCNl7wfWdal78hjqCP+NG3sSeuy oKyqHDN30xK/55PTiqszjqH2Nbu2SilzDR+W1RJrAhpnYvpSKJLF63yFqDtGohd5 LhbcHivZdkJdPHguscq6i+5lWYbSihzIcGS19ee8H9Pr2wmhhQUKvKfhbCd5Nl0E pFqXbL8u4zXAdDSMEZuIpZswraFce7TfC9Kir+/F87DYK09ItNs7wbMhgA/mKuo= =5tuK -----END PGP SIGNATURE----- --------------enig80A7385758E5ADD4E8DB9A50--
