1577         obstack alignment.
1578         * frags.h (frags): Declaration deleted.

1589         section, set frchain_now to absolute_frchain.  Verify that
1590         frch_last and frag_now match on entry and exit.  Initialize

1602         allocation.

1622
1623         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
1624         frag_now_fix instead of accessing obstack info directly.
