* locale/C-ctype.c: New correct data generated by drepper. * Rules: Don't use $(libc.a). Parsing of grouped numbers contributed by Ulrich Drepper. * stdlib/strtol.c (__strtol_internal): Renamed from strtol. Take new flag arg; if nonzero, parse locale-dependent thousands grouping and interpret only the prefix that is correctly grouped. (strtol): Define this to call _strtol_internal with zero for the flag. Use a weak symbol for the definition. * stdlib/strtod.c (strtod, __strtod_internal): Likewise. Check for the exponent of the number overflowing the float format. * stdlib/stdlib.h (__strtof, __strtold): Declarations removed. (__strto{f,d,ld,l,ul,q,uq}_internal): Declare these functions. [__OPTIMIZE__]: Define inline functions calling those. * stdlib/grouping.h: New file, written by drepper. * stdlib/Makefile (distribute): Add grouping.h. * stdio/vfscanf.c: Grok %' modifier to numeric conversions. Call __strtoX_internal with the grouping flag set iff the modifier is present. Wed Mar 15 00:40:54 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/generic/memchr.c: Fix typos: limit.h -> limits.h. * mach/Machrules: Produce static deps for all object flavors. [interface-library]: Remove all these variables and rules. ($(interface-library)-routines): Define this variable. (extra-libs): Append $(interface-library) to this. * mach/Makefile (interface-library): Omit .a suffix. * hurd/Makefile: Likewise. Tue Mar 14 23:40:31 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * stdio/internals.c (flushbuf): If !FLUSH_ONLY, don't skip out early if no new data in buffer after priming. * Makerules (object-suffixes, libtypes): Move all these variables to Makeconfig. * Makeconfig (object-suffixes, libtypes): Moved here from Makerules. * Makerules (build-extra-lib): New canned sequence. * sysdeps/mach/hurd/euidaccess.c: Include fcntl.h. Declare ERR; fix uses of FILE and PORT. Remove bogus weak alias for `access'. * sysdeps/mach/hurd/dirfd.c: Include hurd/fd.h and errno.h. Add missing semicolon. * sysdeps/mach/hurd/opendir.c: Include hurd/fd.h. Use a `struct hurd_fd *' temp var, since DIRP->__fd is a `void *'. * sysdeps/mach/hurd/readdir.c: Include hurd/fd.h. * stdlib/wcstombs.c: #if 0 out code for non-ASCII chars until the locale data format is implemented. * sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler): Pass &__sigreturn on the stack to the trampoline code, so it is not position-dependent. * stdio/printf_fp.c (NDEBUG): Define this to disable assert. Don't include <stdarg.h>. (__printf_fp): Last arg ARGS is now `const void **const'; dereference ARGS[0] instead of using va_arg. * locale/setlocale.c: In LC_ALL case, initialize CATEGORY before loop to install data. * locale/loadlocale.c (_nl_category_num_items): Use _NL_ITEM_INDEX to extract number from item code. (_nl_load_locale): Close the descriptor when finished. * malloc/realloc.c (_realloc_internal): Call _malloc_internal in place of malloc. * time/tzfile.c (__tzfile_default): Initialize RULE_STDOFF to zero.
