* Merge from Debian unstable. (Closes LP: #529559) New upstream version. (Closes LP: #355883) This integrates a workaround for a gcc bug. (cf. LP: #375604) Remaining Ubuntu changes: - debian/control, debian/rules: Exclude dietlibc on powerpc/ppc64 and sparc (cf. LP: #381332) - debian/README.Debian, debian/mksh.postinst: Hardcode installing mksh as /bin/sh to false (cf. LP: #348872) but retain debconf infrastructure so that, if set to true in old installations, it will correctly be removed on upgrade
