The conclusion on bug-standards was that this can be done as long as a
release (production or beta) was made in the intermediate year, or there
was public version control in that year.
From the ChangeLogs it appears there were glibc releases for each year
from 1992 to 1997 at least and by 1998 there was public version control.
So I think this means that years 1992 and later can be collapsed (subject
to working out new ways of doing whatever was previously done using
copyright year information), but not any years before 1992 that are
discontiguous with each other or with the 1992 and later years.
