        Fix 980701-1.f (which was producing "unaligned trap"
        on an Alpha running GNU/Linux, as predicted):
        * equiv.c (ffeequiv_layout_local_): Don't bother
        coping with pre-padding of entire area while building
        it; do that instead after the building is done, and
        do it by modifying only the modulo field.  This covers
        the case of alignment stringency being increased without
        lowering the starting offset, unlike the previous changes,
        and even more elegantly than those.

        * target.c (ffetarget_align): Make sure alignments
        are non-zero, just in case.

See ChangeLog.0 for earlier changes.
