Fri May 3 13:32:08 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>cvs/libc-960504

	* intl/Makefile (CPPFLAGS): Change $(nlsdir) to $(i18ndir) in
	LOCALE_ALIAS_PATH.

Fri May  3 03:14:02 1996  Ulrich Drepper  <drepper@cygnus.com>

	* intl/Makefile (routines): Add l10nflist and explodename.
	(distribute): Add loadinfo.h and locale.alias.
	(install-others): New variable to install locale.alias.

	* intl/dcgettext.c, intl/finddomain.c, intl/gettextP.h,
	intl/loadmsgcat.c: Adapt for upcoming gettext-0.10.13.  Some code
	is now shared with the locale implementation.

	* intl/explodename.c, intl/l10nflist.c, intl/loadinfo.h: New file.
        Extracted from finddomain.c.  This is also used in the locale
        implementation.

	* intl/locale.alias: New file.  Locale alias database compatible
        with X Window System's locale alias file.  Can now be used in
        locale and gettext code.

	* libio/stdio.h: Add prototypes for asprint and vasprintf.

	* locale/C-collate.c, locale/C-ctype.c, locale/C-messages.c,
	locale/C-monetary.c, locale/C-numeric.c, locale/C-time.c: Add new
	field in structure with name of locale ("C" in this case).

	* locale/Makefile (routines): Add findlocale.

	* locale/findlocale.c: New file.  Instead of trying to load the
        directly described file we now try to be much smarter when this
        fails.  Use the same code as gettext does.

	* locale/loadlocale.c, locale/setlocale.c: Rewrite to know about
        new loading scheme.

	* locale/localeinfo.h: Adapt prototypes and declarations for new
	setlocale implementation.  Remove definition of u32_t type.  We
	now use u_int32_t from <sys/types.h>.

	* locale/programs/charset.h (ILLEGAL_CHAR_VALUE): Provide type
        with constant.

	* locale/programs/config.h, locale/lc-collate.c,
        locale/localeinfo.h, locale/programs/ld-collate.c,
        locale/programs/ld-ctype.c, locale/programs/ld-messages.c,
        locale/programs/ld-monetary.c, locale/programs/ld-numeric.c,
        locale/programs/ld-time.c, locale/weight.h, string/strcoll.c:
        Change to use u_int32_t and u_int16_t.

	* locale/programs/localedef.c (construct_output_path): Change name
        of output locale to contain normalized form of the character set
        portion.

	* string/Makefile (routines): Add agrz-ctsep and argz-next.
	(tests): Add tst-strlen.

	* string/argz-ctsep.c: New file.  Implement reverse operation
	from argz-stringify.

	* string/argz-next.c: Non-inline version of function from argz.h.

	* string/argz.h, string/envz.h: Make usable as global header file.

	* string/envz.c: Fix declarations to use size_t where prototypes
	say so.

	* string/tst-strlen.c: New file.  Another test for critical
        situation in strlen implementations.

	* sysdeps/i386/i586/strlen.S: Fix bug with highest byte in word
        being zero.

	* wctype/test_wctype.c: Fix controlling comparison after change to
        32 bit character class array.

Fri May  3 12:53:12 1996  Roland McGrath  <roland@delasyd.gnu.ai.mit.edu>

	* sysdeps/unix/sysv/linux/sys/socket.h: Remove spurious doubled line.

Thu May  2 22:50:52 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/getpriority.c: New file.
	* sysdeps/unix/sysv/linux/syscalls.list: Add s_getpriority.

Thu May  2 22:41:31 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/m68k/fpu_control.h (_FPU_DEFAULT):
	Disable all exceptions.

Thu May  2 22:33:14 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/m68k/fpu/e_acos.c, sysdeps/m68k/fpu/e_acosf.c,
	sysdeps/m68k/fpu/e_fmod.c, sysdeps/m68k/fpu/e_fmodf.c,
	sysdeps/m68k/fpu/isinfl.c, sysdeps/m68k/fpu/isnanl.c,
	sysdeps/m68k/fpu/s_atan.c, sysdeps/m68k/fpu/s_atanf.c,
	sysdeps/m68k/fpu/s_frexp.c, sysdeps/m68k/fpu/s_frexpf.c,
	sysdeps/m68k/fpu/s_ilogb.c, sysdeps/m68k/fpu/s_ilogbf.c,
	sysdeps/m68k/fpu/s_isinf.c, sysdeps/m68k/fpu/s_isinff.c,
	sysdeps/m68k/fpu/s_ldexp.c, sysdeps/m68k/fpu/s_ldexpf.c,
	sysdeps/m68k/fpu/s_modf.c, sysdeps/m68k/fpu/s_modff.c: Don't
	define __NO_MATH_INLINES, which is already defined on command
	line.

Thu May  2 22:18:28 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/libm-ieee754/e_j0f.c (__ieee754_j0f, __ieee754_y0f):
	Replace 0x80000000 by 0x48000000.
	* sysdeps/libm-ieee754/e_j1f.c (__ieee754_j1f): Likewise.

Thu May  2 21:30:33 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sunrpc/svc_simple.c: Make global variable pl local to
	registerrpc.

Thu May  2 00:24:04 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* time/Makefile (tz-cflags): New variable.
	(CFLAGS-tzfile.c): New variable.
	(CFLAGS-zic.c): Add $(tz-cflags).
	(tz-cc): Remove variable.
	($(objpfx)tzfile.o, $(objpfx)zic.o): Remove targets.

	* sysdeps/mach/hurd/getcwd.c: Jump out of both loops when we find a
	name, instead of checking for reaching end of buffer, which happens
	when the match is the last entry in the buffer.
