Update.
2000-09-26 Thorsten Kukuk <kukuk@suse.de> * nscd/dbg_log.c (dbg_log): Add missing format string. * catgets/catgets.c (catopen): Use getenv instead of __secure_getenv since we filter out the variable once. * iconv/gconv_conf.c (__gconv_get_path): Likewise. * locale/newlocale.c (__newlocale): Likewise. * locale/setlocale.c (setlocale): Likewise. * malloc/malloc.c (ptmalloc_init): Likewise. * resolv/res_hconf.c (_res_hconf_init): Likewise. * resolv/res_init.c (__res_vinit): Likewise. * time/tzfile.c (__tzfile_read): Likewise. * sysdeps/generic/unsecvars.h: New file. * elf/dl-support.c (non_dynamic_init): Use it here to remove variables. * elf/rtld.c (process_envvars): Likewise. * elf/Makefile (distribute): Add unsecvars.h.
