glibc/libio/tst_putwc.c
Ulrich Drepper 5bef282098 Update.
2000-07-24  Jakub Jelinek  <jakub@redhat.com>

	* libio/wfiledoalloc.c (_IO_wfile_doallocate): Measure size
	in wide characters, not bytes.
	* libio/tst_putwc.c (do_test): Add test for writing lots of data
	into file.

2000-07-22  Bruno Haible  <haible@clisp.cons.org>

	* locale/nl_langinfo.c (nl_langinfo): Accept items belonging to the
	new categories LC_PAPER, LC_NAME, LC_ADDRESS, LC_TELEPHONE,
	LC_MEASUREMENT, LC_IDENTIFICATION.

	* locale/xlocale.h (struct __locale_struct): Increase size of
	__locales array.
	* locale/duplocale.c (__duplocale): Copy newly added categories as
	well.
	* locale/freelocale.c (__freelocale): Free newly added categories.
	* locale/newlocale.c (__newlocale): Fix typo in sanity check.
	If a base is given, use it, don't simply return it.

2000-07-22  Bruno Haible  <haible@clisp.cons.org>

	* crypt/md5-crypt.c (__md5_crypt_r): Avoid gcc warnings: Use pointer
	variables, copied_key and copied_salt, instead of boolean variables.
