* time/strftime.c (strftime: do_number): Initialize PRINTED to MAXDIGITS in case P is null and so sprintf is never actually called. Mon Jul 29 02:46:23 1996 Ulrich Drepper <drepper@cygnus.com> Add support for the to-be-written internationalized regexp. This code must be able to use collation symbols and collation equivalent classes. * locale/C-collate.c (_nl_C_LC_COLLATE_symbol_hash, _nl_C_LC_COLLATE_symbol_strings, _nl_C_LC_COLLATE_symbol_classes): New global variables for collation classes. * locale/categories.def: Add new descriptions for collation symbols and collation classes. * locale/langinfo.h: Add constants for collation symbols and collation classes. * locale/lc-collate.c: Add new global variables for collation symbols and collation classes. (_nl_postload_collate): Initialize new variables. * locale/programs/ld-collate.c: Add code to emit tables for collation symbols and collation classes. * locale/programs/locales.h: Change prototype for `collate_output'. * locale/programs/locfile.c (write_all_categories): Call `collate_output' with new argument. * locale/localeinfo.h: Add declaration for new global vars. (union locale_data_value): New member wstr for `wchar_t' strings. * locale/programs/locale-spec.c: Handle `collate-classes' keyword and print information about available collation classes. * locale/strlen-hash.h: New file. Simple hashing function which takes a string with known length. * locale/Makefile (distribute): Add strlen-hash.h. (locale-modules): New var. Additional files for `locale' program. * locale/C-ctype.c: Rewrite to avoid using string for giving values which are of type `u_int32_t'. Correct entry for EOF in toupper and tolower tables. * locale/loadlocale.c (_nl_load_locale): Add cast to prevent warning. * locale/programs/ld-ctype.c (ctype_output): Add code to make sure that all tables in binary file are words aligned. * locale/programs/locfile.c (write_locale_data): Correct handling of LC_MESSAGES locale. Create directory if necessary. * locale/setlocale.c (setlocale): Add cast to avoid warning. * string/string.h: Add prototype for `__strndup'. Wed Jul 24 19:10:00 1996 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * wcsmbs/mbrtowc.c: Remove unused variable. Sun Jul 28 22:40:25 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu> * sysdeps/unix/sysv/linux/configure.in (LIBC_LINUX_VERSION): Update to 2.0.10; some problems were reported with an earlier version, and this one is known to work. * sysdeps/generic/dl-sysdep.c (__libc_enable_secure): New variable. * sysdeps/mach/hurd/dl-sysdep.c: Likewise.
