Subject: 	* java/text/SimpleDateFormat.java 
 (SimpleDateFormat(String,DateFormatSymbols)): Call 	computeCenturyStart().
 	* gnu/java/locale/LocaleInformation_de.java (word_breaks, 
 sentence_breaks, line_breaks): Removed. 	(collation_rules): Use `k,K',
 not `j,K'.  Don't using leading 	`-'.  Use `0<1', not `0,1'.  Use
 `9<A', not `9A'. 	* gnu/java/locale/LocaleInformation_nl.java: Likewise.
 	* gnu/java/locale/LocaleInformation_en.java: Likewise. 	*
 java/text/DateFormatSymbols.java: Merged with libgcj. 	*
 java/text/StringCharacterIterator.java: Reindented and merged 	with libgcj. 
 (StringCharacterIterator(String,int,int,int)): Simplified. 	(current):
 Likewise. 	(next): Likewise. 	(previous): Likewise. 	(last):
 Likewise. 	(equals): Likewise. 	(setText): Now public.  Also sets all
 fields. 	* java/text/RuleBasedCollator.java (clone): Rewrote. 	*
 java/text/Collator.java: Mostly merged with libgcj. 	*
 java/text/MessageFormat.java: Merged with libgcj. 	*
 java/text/FieldPosition.java: Reindented.  Merged with libgcj. 	*
 java/text/ParsePosition.java: Reindented.  Merged with libgcj. 	*
 java/text/Format.java: Reindented.  Merged with libgcj. 	(parseObject):
 Doesn't throw exception on error. 	* java/text/CharacterIterator.java:
 Reindented. 	* java/text/ChoiceFormat.java: Merged with libgcj. 	*
 gnu/java/text/Makefile.am: New file. 	* gnu/java/Makefile.am (SUBDIRS):
 Added text. 	* configure.in (AC_OUTPUT): Added gnu/java/text/Makefile. 
 * gnu/java/text/BaseBreakIterator.java: New file from libgcj. 	*
 gnu/java/text/CharacterBreakIterator.java: Likewise. 	*
 gnu/java/text/LineBreakIterator.java: Likewise. 	*
 gnu/java/text/SentenceBreakIterator.java: Likewise. 	*
 gnu/java/text/WordBreakIterator.java: Likewise. 	*
 java/text/BreakIterator.java: Merged with libgcj. 	*
 java/text/DefaultBreakIterator.java: Removed. 	*
 java/text/DecimalFormatSymbols.java: Merged with libgcj. 	*
 java/text/DateFormat.java: Merged with libgcj. 	*
 gnu/java/locale/Makefile.am (EXTRA_DIST): Added new file. 	*
 gnu/java/locale/LocaleInformation_en.java: Removed US-specific 
 entries. 	(collation_rules): Use `k,K', not `j,K'. 	*
