Major merge with Classpath.
Removed many duplicate files. * HACKING: Updated.x * classpath: Imported new directory. * standard.omit: New file. * Makefile.in, aclocal.m4, configure: Rebuilt. * sources.am: New file. * configure.ac: Run Classpath configure script. Moved code around to support. Disable xlib AWT peers (temporarily). * Makefile.am (SUBDIRS): Added 'classpath' (JAVAC): Removed. (AM_CPPFLAGS): Added more -I options. (BOOTCLASSPATH): Simplified. Completely redid how sources are built. Include sources.am. * include/Makefile.am (tool_include__HEADERS): Removed jni.h. * include/jni.h: Removed (in Classpath). * scripts/classes.pl: Updated to look at built classes. * scripts/makemake.tcl: New file. * testsuite/libjava.jni/jni.exp (gcj_jni_compile_c_to_so): Added -I options. (gcj_jni_invocation_compile_c_to_binary): Likewise. From-SVN: r102082

-/**
- * This class is used to differentiate different orientations for text layout.
- * It controls whether text flows left-to-right or right-to-left, and whether
- * lines are horizontal or vertical, as in this table:<br>
- * <pre>
- * LT RT TL TR
- * A B C C B A A D G G D A
- * D E F F E D B E H H E B
- * G H I I H G C F I I F C
- * </pre>
- * <b>LT</b> languages are most common (left-to-right lines, top-to-bottom).
- * This includes Western European languages, and optionally includes Japanese,
- * Chinese, and Korean. <b>RT</b> languages (right-to-left lines,
- * top-to-bottom) are mainly middle eastern, such as Hebrew and Arabic.
- * <b>TR</b> languages flow top-to-bottom in a line, right-to-left, and are
- * the basis of Japanese, Chinese, and Korean. Finally, <b>TL</b> languages
- * flow top-to-bottom in a line, left-to-right, as in Mongolian.
- *
- * <p>This is a pretty poor excuse for a type-safe enum, since it is not
- * guaranteed that orientation objects are unique (thanks to serialization),
- * yet there is no equals() method. You would be wise to compare the output
- * of isHorizontal() and isLeftToRight() rather than comparing objects with
- * ==, especially since more constants may be added in the future.

- * @since 1.0
- * @status updated to 1.4
