I've reproduced this on a Fedora 16 x86_64 host.

OK, attached.

As root I see:

# echo x > foo
# chmod a-w foo
# test ! -w foo || echo still writable
still writable
# (echo y > foo) && echo can write to unwritable
can write to unwritable
# cat foo
y

As a regular user, I see:

$ echo x > foo
$ chmod a-w foo
$ test ! -w foo || echo still writable
$ (echo y > foo) && echo can write to unwritable
bash: foo: Permission denied
$ cat foo
x

This is as I'd expect, as root can always write to a file, regardless of
permissions.  Due to our particular build environment, automake is built
and tested as the root user in a chroot environment.

Regards,

Matt.
