+ * section.c (_bfd_strip_section_from_output): Add info parameter.
+ If it passed as non-NULL, use it to check whether any input BFD
+ has an input section which uses this output section. Change all

+ * bfd-in.h: Move declarations of bfd_get_elf_phdr_upper_bound and
+ bfd_get_elf_phdrs in from bfd-in2.h, correcting patch of
+ 1999-11-29.
