Hm.  If that fixes it, it implies that all the other support for
pre-1970 dates is still there (notably, entries in the timezone tables).

Should we assume that future glibc releases will rip out the timezone
database entries and other support for pre-1970 dates?  Or is the
breakage going to stop with mktime?
