* 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.
