	* configure.ac: Correct description of PORTABLE_NATIVE_SYNC
	config.h definition.

	* native/jni/gtk-peer/gnu_java_awt_peer_gtk_GtkMainThread.c,
	include/gnu_java_awt_peer_gtk_GtkMainThread.h
	(Java_gnu_java_awt_peer_gtk_GtkMainThread_gtkInit): New argument,
	portableNativeSync.  Delegate PORTABLE_NATIVE_SYNC work to
	init_glib_threads.
	(init_glib_threads): New function.

	* doc/vmintegration.texinfo (VM Threading Model): Explain the
	gnu.classpath.awt.gtk.portable.native.sync system property.
