Currently, build-many-glibcs.py uses (by default) release versions of most components other than glibc itself, release branches for gcc / binutils. Should the most recent releases from ftp.gnu.org of mig / gnumach / hurd be used for building current glibc for Hurd, or is it preferable or necessary to use newer development versions of those components? -- Joseph S.
