+ * Revision 2.2 1996/03/10 01:06:01 pavel
+ * Replaced HUGE_VAL with DBL_MAX, since some systems (e.g., BSDi 1.1)
+ * mis-define the former as positive infinity. Release 1.8.0.
+ *
+ * Revision 2.1 1996/02/08 06:04:22 pavel
+ * Updated copyright notice for 1996. Added inclusion of <math.h> for all of
+ * the standard math functions. Added IS_REAL() check for NaNs and
+ * infinities. Release 1.8.0beta1.
+ *
+ * Revision 2.0 1995/11/30 05:15:40 pavel
+ * New baseline version, corresponding to release 1.8.0alpha1.
