Probably because you switched systems or PATH, and are no longer using the GNU coreutils version of uniq. I upgraded recently from Debian Sarge to Ubuntu Dapper, and I noticed that the -W (note the caps!) flag had disappeared. Maybe it was a Debian distro patch. Paul Eggert has mentioned that upstream uniq has never had a -W flag. Would you be receptive to a patch? I'm happy to write one.

error: conflicting types for 'tee'

Re: make install using -j
Ralf Wildenhues [EMAIL PROTECTED] writes in
http://lists.gnu.org/archive/html/bug-automake/2006-06/msg00025.html:
Not sure about an easy way to fix the first bug as well here.
* lib/install-sh: HP-UX 11.23 `mkdir -m u=rwx,[...],u+wx -p'
may exit 0 but create intermediate directories with bogus
permissions. So change the `$mkdirprog -m $test_mode' test to
create actual directories, and test for readability of the
intermediate one. Clean up afterwards.
This patch assumes the working directory is writable, which isn't a
safe assumption. Also, it won't work as root, since 'test -r D'
succeeds as root even if D has mode d-wx-w--w-. And, as you mentioned,
the patch doesn't work around the mkdir -m u=rwx,g=rx,o=rx -p -- foo/bar
bug on UP-UX 11.23 and IRIX 6.5 that you reported in
http://lists.gnu.org/archive/html/bug-automake/2006-06/msg00024.html.
On my list of things to do is to fix GNU install to be safer and more
compatible with BSD install, with respect to the modes of intermediate
directories and temporary files. Among other things, GNU install
should use mode 755 as modified by the umask to create temporary
directories, instead of what it currently does (which is an
undocumented algorithm that is similar to, but not quite identical to,
mkdir -p's algorithm). I'll CC: this message to bug-coreutils to give
them a heads-up on this.
Anyway, to get back to install-sh: it needs a similar patch, so your
email prompted me to write it. As a side effect I think this patch
works around both bugs you reported. So I propose the following
Automake patch instead. Does it work for you?

[bug #16913] sleep fails to detect overflow on amd64 / linux 2.6
Update of bug #16913 (project coreutils): Status:None = Wont Fix Open/Closed:Open = Closed ___ Follow-up Comment #1: xnanosleep's overflow checking merely catches the usual problems with integer overflow in xnanosleep's own calculations. It's not designed to work around bugs in the implementation of nanosleep. Offhand, I don't see an easy way to work around this bug so I'd say you just need to get your kernel fixed. (In the meantime you can rest easy knowing that coreutils sleep is a good way to check for the kernel bug. :-) ___ Reply to this item at: http://savannah.gnu.org/bugs/?func=detailitemitem_id=16913 ___ Message sent via/by Savannah http://savannah.gnu.org/ ___ Bug-coreutils mailing list Bug-coreutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-coreutils
