3907         obstack alignment.
3908         * frags.h (frags): Declaration deleted.

3920         frch_last and frag_now match on entry and exit.  Initialize

3932         allocation.

3952
3953         * config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
3954         frag_now_fix instead of accessing obstack info directly.
