Update.
2004-09-17 Ulrich Drepper <drepper@redhat.com> * include/link.h (struct link_map): Add l_used element. * sysdeps/generic/ldsodefs.h: Define DL_DEBUG_UNUSED. * elf/rtld.c (process_dl_debug): Recognize unused. (dl_main): When unused debug flag is set check for unused direct dependencies. When printing dependencies and SONAME starts with /, omit the SONAME => part. * elf/dl-lookup.c (_dl_lookup_symbol_x): Mark object in which the symbol has been found as used. * elf/ldd.bash.in: Add -u option.
