Subject: [PATCH] 	* aoutx.h (NAME(aout,find_nearest_line)):  Handle the
 case 	of two N_SO stabs, one for directory, and one for filename.

	* bfd-in.h (print_vma):  Factor out duplicate definition.

	Exit a little more gracefully when malloc returns NULL.
	* libbfd.c: New function bfd_xmalloc (malloc wrapper).
	* opncls.c, syms.c, bout.c, aoutx.h:  Replace malloc by bfd_xmalloc.
	* libbfd.h: Rre-generated due to libbfd.c update.
