I investigated some more, and the MNT_DETACH was introduced after
glibc 2.7, which is the version in Debian Lenny on my laptop.  It is
present in 2.10 in the Debian unstable repository.  This patch might
solve the issue.  It solve the build problem, at least.  I am unsure
which kernel have a umount2() call that understand this argument.
