+	* native/jni/java-lang/java_lang_VMDouble.c (Java_java_lang_VMDouble_longBitsToDouble)
+	(Java_java_lang_VMDouble_doubleToRawLongBits): Added implementation using ieee754.h.
+	Include ieee754.h if available. Added workaround for glibc BIG_ENDIAN bug on arm-linux.
+	
+	* configure.ac: Check for ieee754.h
