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.
