	delta.

	* java/lang/e_asin.c (__ieee754_asin): Initialize variable t.

	* java/lang/e_exp.c (__ieee754_exp): Initialize variables hi, lo
	and k.

	* java/lang/e_rem_pio2.c (__ieee754_rem_pio2): Initialize
	uninitialized variable z.

	* gnu/java/net/natPlainDatagramSocketImplPosix.cc (mcastGrp): Ifdef
	possible unused variables.

	* gnu/java/nio/natPipeImplPosix.cc (init): Remove self.
