reasonable mode until "ar x" is smart enough to skip it (fixes
	gcc/libgcc.a builds on mips-ecoff targets
	* coffcode.h (styp_to_sec_flags): Explain how COMDATs are supposed
	to work.  Hack to support MS import libraries, which use different
	COMDAT types than GNU.
	(coff_slurp_symbol_table): C_SECTION symbols are local; they refer
	to implied zero-length sections (see peicode below)
	* coffgen.c (coff_get_normalized_symtab): Properly read long MS
	filename symbols, which use one *or more* auxents.
	* coffswap.h (coff_swap_aux_in): ditto
	* peicode.h (coff_swap_sym_in): Build the implied zero-length
	sections
