+* From: niles@fan745.gsfc.nasa.gov
+* To: fortran@gnu.org
+* Cc: niles@fan745.gsfc.nasa.gov
+* Subject: problem with DNINT() on Linux/Alpha.
+* Date: Sun, 06 Jun 1999 16:39:35 -0400
+* X-UIDL: 6aa9208d7bda8b6182a095dfd37016b7
+
+      IF (DNINT(0.0D0) .NE. 0.) CALL ABORT
+      STOP
+      END
+
+* Result on Linux/i386: " 0."  (and every other computer!)
+* Result on Linux/alpha: " 3.6028797E+16"
+
+* It seems to work fine if I change it to the generic NINT().  Probably
+* a name pollution problem in the new C library, but it seems bad. no?
+
+* 	Thanks,
+* 	Rick Niles.
