Update.

1999-04-13  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* libio/obprintf.c (_IO_obstack_overflow): Put the write end at
	the real end of the chunk, not some random point inbetween.
	(_IO_obstack_xsputn): Likewise.  Actually copy the data into the
	obstack when growing.  Use fast version of obstack_blank when
	shrinking.
	(struct _IO_obstack_file): Use _IO_FILE_plus instead of explicitly
	allocating the vtable pointer.
	(_IO_obstack_vprintf): Adjust for above change and avoid
	unnecessary casts.  Use fast version of obstack_blank when
	shrinking.
	Fixes PR libc/1075.
