[BZ #2337]

2006-12-13  Ulrich Drepper  <drepper@redhat.com>
	[BZ #2337]
	* libio/Makefile (tests): Add tst-setvbuf1.
	* libio/tst-setvbuf1.c: New file.

2006-12-08  Jakub Jelinek  <jakub@redhat.com>

	[BZ #2337]
	* libio/genops.c (__uflow): Fix a typo.
	* libio/wfiledoalloc.c (_IO_wfile_doallocate): Don't stat
	nor set _IO_LINE_BUF bit here.  Size the wide buffer based on
	the narrow buffer size.

2006-11-24  Jakub Jelinek  <jakub@redhat.com>

	[BZ #2337]
	* libio/libio.h (_IO_FLAGS2_USER_WBUF): Define.
	* libio/wgenops.c (_IO_wsetb, _IO_wdefault_finish): Test and set
	_IO_FLAGS2_USER_WBUF bit in _flags2 instead of _IO_USER_BUF bit
	in _flags.
	* libio/wstrops.c (_IO_wstr_overflow, enlarge_userbuf,
	_IO_wstr_finish): Likewise.
	* libio/wmemstream.c (open_wmemstream): Likewise.
	* libio/fileops.c (_IO_new_file_close_it): Call _IO_set[bgp]
	even for wide streams.
