Right. The immediate reason is because config.guess and config.sub are not
being updated. Once they are updated, configure will not fail. When I copy them,
manually, from /usr/share/libtool/config/, the build does not fail.

My apologies, it was a confusion of my part. I was looking at the git tree.
The tarball does come with configure. But the config.{guess,sub} that come with
it are up-to-date, differently of what comes with the debian src package.
I generated a diff from them, which is attached.
Also, the version I have here is not 4.2.0-rc1, it is the one found at the git
repository I mentioned. Is that not correct?

Ok. Just clarifying that what actually fails is the debian package, exclusively.
The ones found in xfs.org (actually oss.sgi.com/xfs) build flawlessly.

Originally I used sbuild, but manually this is what I do:

# apt-get source xfsprogs
# cd xfsprogs-3.2.4/
# apt-get build-dep xfsprogs
...
# dpkg-buildpackage
I am attaching the build log because it is a bit long.

Yes, I changed that line 1315 in /usr/share/aclocal/libtool.m4 to look the same
as you showed, but the build failed anyway.

I understand that.
A correction though: mine builds from the official xfsprogs source or tarballs
without problems too.
It is the Debian source package that fails, exclusively.

What is causing it is: the old files config.guess and config.sub in the source 
package. Whether shipping updated ones or not shipping the configure file would
be the quick solution to this. Again, it is an exclusive problem with the
Debian package.

I am curious about something I have just noticed (while writing this e-mail).
Running apt-get source xfsprogs gets a tarball xfsprogs_3.2.4.tar.gz
Shouldn't it be the exact same file I get from:
http://ftp.br.debian.org/debian/pool/main/x/xfsprogs/xfsprogs_3.2.4.tar.gz
Because they differ. And the latter does not fail at all.

I am sorry for any confusion I might be causing :)

Thanks and regards.
