[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.
