Subject: Patches for glibc to add proper lchown() support for Alphas
Message-ID: <Pine.LNX.3.96.981026130255.25937A-100000@beezer.med.miami.edu>
MIME-Version: 1.0
Content-Type: TEXT/PLAIN; charset=US-ASCII
Package: glibc
Version: 2.0.7u-3
Below is a patch for proper lchown() support on Alphas. It auto-detects
lchown() support in the kernel and activates based on that. This is
necessary for dpkg to operate properly under 2.1.x kernels on Alphas.
Thanks!
