2000-01-31  Scott Bambrough  <scottb@netwinder.org>

	* gcc/java/gjavah.c (D_NAN_MASK): Alternate definition required when
	HOST_FLOAT_WORDS_BIG_ENDIAN is defined to be 1.
	(java_float_finite): Convert to use union Word from javaop.h.
	(java_double_finite): Convert to use union DWord from javaop.h.
