Update.
1999-01-11 Ulrich Drepper <drepper@cygnus.com> * ctype/Versions [GLIBC_2.0]: Export __ctype32_b. * include/wctype.h: Declare __iswctype. * stdio-common/vfscanf.c (__vfscanf): Use __iswspace instead of iswspace. * wctype/Makefile (routines): Add wcextra_l. * wctype/wcextra.c (iswblank): Implement function here and don't use __iswctype. (__iswblank_l): Move definition to... * wctype/wcextra_l.c: ...here. New file. * wctype/wcfuncs.c: Really implement functions and don't call __iswctype or __towctrans. * wctype/wctype.h: Change isw* and tow* macros. Don't call __iswctype or __towctrans. Instead optimize constant argument case. * iconv/gconv.h: Fix typos. * iconv/skeleton.c: Fix typos. Optimize init function a bit. Correctly emit escape sequence to return to initial state in conversion function. * iconvdata/iso-2022-jp.c (gconv_init): Correctly initialize max_needed_to element. * manual/mbyte.texi: Removed. This is now described in charset.texi. * manual/charset.texi: New file. * manual/Makefile (chapters): Replace mbyte by charset. * manual/ctype.texi: Document wide character functions. * manual/intro.texi: Fix reference to mbyte chapter. * manual/lang.texi: Likewise. * manual/locale.texi: Likewise. * manual/stdio.texi: Likewise. * manual/string.texi: Fix @node line for new charset chapter. * manual/libc.texinfo (UPDATED): Updated. Also update copyright years. * manual/memory.texi (savestring): Optimize code to give a good example. * manual/filesys.texi: Fix wording. Patches by Jim Meyering. * nscd/nscd_getgr_r.c: Include stdint.h to get uintptr_t definition. * nscd/nscd_getpw_r.c: Likewise. * nscd/nscd_gethst_r.c: Likewise. * stdlib/stdtold_l.c: Always include xlocale.h. 1999-01-11 Geoffrey Keating <geoffk@ozemail.com.au> * stdlib/fpioconst.h (LDBL_MAX_10_EXP_LOG): Define to be same as DBL_MAX_10_EXP_LOG if there is no long double. (_fpioconst_pow10): Always use size as LDBL_MAX_10_EXP_LOG to match printf_fp.c. 1999-01-10 Andreas Jaeger <aj@arthur.rhein-neckar.de> * timezone/Makefile ($(testdata)/GB): Changed to ... ($(testdata)/Europe/London): ... for tst-timezone test. ($(objpfx)tst-timezone.out): Change GB to Europe/London. * timezone/tst-timezone.c (main): Enable DST switching test, change GB to Europe/London. 1999-01-10 Philip Blundell <philb@gnu.org> * socket/Makefile (headers): Remove bits/sockunion.h. 1999-01-09 Philip Blundell <philb@gnu.org> * socket/sys/socket.h: Don't include <bits/sockunion.h>. * sysdeps/generic/bits/sockunion.h: Deleted. * sysdeps/unix/sysv/linux/bits/sockunion.h: Likewise. 1999-01-08 H.J. Lu <hjl@gnu.org> * io/fts.c (fts_close): Don't access memory after having it freed.
