1999-02-06 Ulrich Drepper <drepper@cygnus.com> * Versions.def: Add versions for ld.so. * csu/Versions: Remove __libc_stack_end here. * elf/Versions: Split libc definitions in libc and ld.so definitions. * elf/Makefile (ld-map): Change to ld.so.map. * scripts/versions.awk: Recognize dot in library names. * ctype/ctype.h: Remove definitions of __tolower and __toupper. Don't use __tolower and __toupper in inline functions. Add optimizing macros for tolower and toupper. * ctype/ctype-extn.c (_tolower): Don't use __tolower. (_toupper): Don't use __toupper. * ctype/ctype.c (tolower): Don't use __tolower. (toupper): Don't use toupper. * nscd/cache.c (prune_cache): Correct printing of debugging messages. * resolv/Versions (libresolv): Export __ns_name_unpack and __ns_name_ntop. * resolv/res_comp.c: Rename ns_name_unpack to __ns_name_unpack and make it global. Change all users. Similar for ns_name_ntop. * resolv/nss_dns/dns-host.c: Don't use dn_expand when extracting in user-provided buffer. Use __ns_name_unpack and __ns_name_ntop directly to detect too small buffer. * stdio-common/Makefile (tests): Add scanf12. * stdio-common/scanf12.c: New file. * stdio-common/scanf12.input: New file. * stdio-common/vfscanf.c (__vfscanf): Handle +/- at beginning of floating-point correctly if the number is invalid. * stdio-common/vfscanf.c: Don't use non-reentrant multibyte conversion * stdio-common/printf_fphex.c: Likewise. * stdio-common/vfprintf.c: Likewise. See ChangeLog.9 for earlier changes.
