* locale/programs/charmap.c (charmap_read): If encoding is found not ASCII compatible, set enc_not_ascii_compatible. * locale/programs/charmap.h: Declare enc_not_ascii_compatible. * locale/programs/ld-ctype.c (ctype_startup): If enc_not_ascii_compatible is set, initialize to_nonascii to 1. 2003-11-22 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (process_envvars): Only honor LD_USE_LOAD_BIAS if !__libc_enable_secure. * sysdeps/generic/ldsodefs.h (_dl_use_load_bias): New _rtld_global field. * elf/rtld.c (_rtld_global): Initialize _dl_use_load_bias field. (dl_main): Set GL(dl_use_load_bias) default. (process_envvars): Set GL(dl_use_load_bias) from LD_USE_LOAD_BIAS. Add EXTRA_LD_ENVVARS_13. * elf/dl-support.c (_dl_use_load_bias): New variable. * elf/dl-load.c (_dl_map_object_from_fd): Mask c->mapstart with GL(dl_use_load_bias). * sysdeps/generic/unsecvars.h (UNSECURE_ENVVARS): Add LD_USE_LOAD_BIAS. * sysdeps/unix/sysv/linux/dl-librecon.h (EXTRA_LD_ENVVARS): Remove. (EXTRA_LD_ENVVARS_LINUX): Renamed to... (EXTRA_LD_ENVVARS_13): ... this. Remove case at the beginning. * sysdeps/unix/sysv/linux/i386/dl-librecon.h (EXTRA_LD_ENVVARS): Don't undefine first.
