* 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.
