2004-09-24  Michael Koch  <konqueror@gmx.de>

	* gnu/java/nio/PipeImpl.java: Use VMPipe for native stuff.
	* gnu/java/nio/SelectorImpl.java: Use VMSelector for native stuff.
	* gnu/java/nio/VMPipe.java,
	gnu/java/nio/VMSelector.java:
	New files.
	* gnu/java/nio/natPipeImplEcos.cc,
	gnu/java/nio/natPipeImplPosix.cc,
	gnu/java/nio/natPipeImplWin32.cc:
	Ported to VMPipe.
	* gnu/java/nio/natSelectorImplEcos.cc,
	gnu/java/nio/natSelectorImplPosix.cc,
	gnu/java/nio/natSelectorImplWin32.cc:
	Ported to VMSelector.
	* Makefile.am: Added new files gnu/java/nio/VMPipe.java and
	gnu/java/nio/VMSelector.java.
	* Makefile.in: Regenerated.
