1624         entry and exit, and that old frag_now has non-zero type.  Replace
1625         "know" uses with "assert".  Use frag_alloc instead of mucking with
1626         obstack alignment.
1627         * frags.h (frags): Declaration deleted.

1635         (subseg_set_rest): Save and restore frag_now in frch_frag_now
1636         field of frchainS.  Don't create new frags on section switch, and

1638         section, set frchain_now to absolute_frchain.  Verify that
1639         frch_last and frag_now match on entry and exit.  Initialize
1640         per-chain obstack, and under gcc, set required alignment to that
1641         needed by fragS structure.

1651         allocation.
