* intl/Makefile (copysrc): Add missing > in sed cmd.
Sat Mar 23 17:52:49 1996 Ulrich Drepper <drepper@gnu.ai.mit.edu>
* Makeconfig: Rename Makefile variable nlsdir to i18ndir and
change value to $(datadir)/i18n. `nls' is not an appropriate
name.
* Makefile (subdirs): Add new subdir wctype.
* ctype/ctype-info.c: Add new global variable __ctype_names
and initialize from _nl_C_LC_CTYPE.
* ctype/ctype.h: In P1003.3b/D11 `alnum' is a separate character
class. Use bit 11.
[_ISbit]: Protect definition of bitmasks because they are also
used in wctype.h.
* libio/genops.c (_IO_sputbackc, _IO_sungetc): Clear EOF flag
after successfully pushing back a character.
Fundamental changes in locale implementation. Almost nothing
from the old code is used anymore.

extended LC_CTYPE and LC_COLLATE implementation.
* locale/simple-hash.c, locale/simple-hash.h, locale/xmalloc.c,
locale/xstrdup.c: Helper functions for locale related programs.

locale/lc-numeric.c, locale/lc-time.c: New implementation of locale
functions, and new generated "C" locale data.
* locale/loadlocale.c: Now handles word fields in locale binary
automatically by changing the endianess if necessary.
* locale/localeinfo.h (LIMAGIC): Changed magic number because
of incompatible changes.
(locale_data): Changed definition to allow word as a value type.
(coll_sort_rule): Values for collation sorting mode.
(_NL_CURRENT_WORD): New macro to access word value of locale entry.
(__collate_table, __collate_extra): Declare new global variables
for collation tables.

< 10^-1. Reported by Bill Metzenthen.

* string/strcoll.c, string/strxfrm.c: Real implementation of
string collation according to ISO C.
* wctype/Makefile, wctype/cname-lookup.h, wctype/iswctype.c,
wctype/test_wctype.c, wctype/towctrans.c, wctype/wcfuncs.c,
