	* Regenerate auto* files.

	* include/jvm.h:
	* jni-libjvm.cc (Jv_JNI_InvokeFunctions): Rename type.
	* jni.cc (_Jv_JNIFunctions, _Jv_JNI_InvokeFunctions): Likewise.
	* jni.cc (_Jv_JNI_CallAnyMethodA, _Jv_JNI_CallAnyVoidMethodA,
	_Jv_JNI_CallMethodA, _Jv_JNI_CallVoidMethodA,
	_Jv_JNI_CallStaticMethodA, _Jv_JNI_CallStaticVoidMethodA,
	_Jv_JNI_NewObjectA, _Jv_JNI_SetPrimitiveArrayRegion): Constify
	jvalue parameter.
	* java/lang/reflect/natMethod.cc (_Jv_CallAnyMethodA): Likewise.

	* java/lang/VMFloat.java (toString, parseFloat): New.

	* gnu/awt/xlib/XToolkit.java (setAlwaysOnTop, isModalityTypeSupported,
	isModalExclusionTypeSupported): New (stub only).
	* gnu/awt/xlib/XCanvasPeer.java (requestFocus): Likewise.
	* gnu/awt/xlib/XFramePeer.java (updateMinimumSize, updateIconImages,
	updateFocusableWindowState, setModalBlocked, getBoundsPrivate,
	setAlwaysOnTop): Likewise.
	* gnu/awt/xlib/XFontPeer.java (canDisplay): Update signature.

	* scripts/makemake.tcl: Ignore gnu/javax/sound/sampled/gstreamer,
	ignore javax.sound.sampled.spi.MixerProvider, ignore .in files.

	* HACKING: Mention --enable-gstreamer-peer, removal of generated files.
