	* frags.h (frags): Declaration deleted.
	* subsegs.h (struct frchain): Add new field frch_frag_now.

	not initialize frags obstack.  Set frag_now to point to
	dummy_obstack.  Initialize absolute_frchain.
	(subseg_set_rest): Save and restore frag_now in frch_frag_now
	field of frchainS.  Don't create new frags on section switch, and

	frch_last and frag_now match on entry and exit.  Initialize
	per-chain obstack, and under gcc, set required alignment to that
	needed by fragS structure.

	* stabs.c (get_stab_string_offset): Only copy input string if a
	fresh copy is needed, not if the section already exists.

	testsuite directory.

	files within it that would be generated by running tests.

	* config/tc-hppa.c (hppa_elf_mark_end_of_function): Call
