Tue Jan 26 11:43:14 1993 Ian Lance Taylor (ian@cygnus.com) 

* section.c (SEC_IS_COMMON): New section flag, needed for MIPS
	ECOFF which has two common sections.
	(bfd_com_section): Set SEC_IS_COMMON flag.
	* bfd-in.h (bfd_is_com_section): New macro to test SEC_IS_COMMON.
	* aoutx.h, archive.c, bout.c, coff-a29k.c, coff-m88k.c,
	coff-mips.c, coffgen.c, ieee.c, oasys.c, reloc.c, syms.: Use
	bfd_is_com_section macro rather than checking for equality to
	bfd_com_section.
