1999-07-01  Warren Levy  <warrenl@cygnus.com>
	* gnu/gcj/convert/BytesToUnicode.java (read): Changed outlength
	to count and revised comments to match.
	* gnu/gcj/convert/Input_EUCJIS.java (read): Same as Input_8859_1.java.
	* gnu/gcj/convert/Input_JavaSrc.java (read): ditto.
	* gnu/gcj/convert/Input_SJIS.java (read): ditto.
	* gnu/gcj/convert/Input_UTF8.java (read): ditto.
	* gnu/gcj/convert/natInput_EUCJIS.cc (read): ditto.
	* gnu/gcj/convert/natInput_SJIS.cc (read): ditto.
1999-07-01  John-Marc Chandonia  <jmc@cmpharm.ucsf.edu>
	* gnu/gcj/convert/Input_8859_1.java (read): Use 3rd parameter
	properly as count rather than outlength.
	* java/io/BufferedOutputStream.java (write(byte[],int,int): Flush
	output on overflow rather than buffer fill.
	* java/io/BufferedReader.java (fill): Don't clear out the buffer
	if markPos is 0 and there is still room in the buffer.
