* config/obj-coff.c (coff_frob_symbol): Always update set_end with 

next_set_end even if the end symbol is being discarded.

	* gasp.c: Add ATTRIBUTE_UNUSED as needed for non-BFD_ASSEMBLER.
	* output-file.c, symbols.c, config/tc-i386.c: Likewise.
	* config/obj-coff.c: Likewise.
	(seg_info_type): Remove.
	(seg_info_off_by_4): Change to array of segT.
	(s_get_segment): Adjust accordingly.
	(obj_pseudo_table): Fully initialize sentinel entry.

/* Section stuff
/* When not using BFD_ASSEMBLER, we permit up to 40 sections.
We allow more than just the standard 3 sections, infact, we allow
40 sections, (though the usual three have to be there).
This array maps a COFF section number into a gas section number.
Because COFF uses negative section numbers, you must add 4 to the
COFF section number when indexing into this array; this is done via
the SEG_INFO_FROM_SECTION_NUMBER macro. This must correspond to
seg_N_TYPE. */
This structure performs the mappings for us:
