Checking win32.has_acls() and using GENERIC_WRITE caused a regression in utimes
(). The new upstream automake-1.9.5 tarball contains a read-only file (mode
0444). Before the 20050211 snapshot, when utimes() is still using
FILE_WRITE_ATTRIBUTES, tar does just fine at adjusting the timestamp of that
file when unpacking to an NFS-mounted directory. However, with the current
code, when I tried to unpack, tar is no longer able to touch the timestamps of
the read-only file because GENERIC_WRITE requires write access for at least one
of user, group, and other, even though touching the timestamp does not.
$ tar xjvf automake-1.9.5.tar.bz2
...
automake-1.9.5/m4/amversion.m4
tar: automake-1.9.5/m4/amversion.m4: Cannot utime: Permission denied
...
tar: Error exit delayed from previous errors
$ echo $?
