Thu Mar 16 00:04:41 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
	* 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.
