Update.

2004-04-20  Jakub Jelinek  <jakub@redhat.com>
	* stdio-common/vfscanf.c (_IO_vfscanf): When skipping whitespace,
	do input_error () instead of conv_error () and don't look at errno.
	Don't eat any whitespace before %% if skip_space == 0.
	* stdio-common/tst-sscanf.c (int_tests): New array.
	(main): Run int_tests.
See ChangeLog.14 for earlier changes.
