Update.
2002-12-18 Ulrich Drepper <drepper@redhat.com> * elf/dl-support.c [NEED_DL_SYSINFO]: Define and initialize _dl_sysinfo. [DL_SYSINFO_IMPLEMENTATION]: If defined use it to generate the needed code. * elf/rtld.c [DL_NEED_SYSINFO]: Initialize _dl_sysinfo element of _rtld_global. [DL_SYSINFO_IMPLEMENTATION]: If defined use it to generate the needed code. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start) [NEED_DL_SYSINFO]: Check for AT_SYSINFO and set _dl_sysinfo appropriately. * sysdeps/generic/ldsodefs.h (struct rtld_global) [NEED_DL_SYSINFO]: Add _dl_sysinfo.
