+Warning!  Your libc has not yet been patched so that its "%Lf" format for
+printing long doubles shows all the significant digits.  You will get errors
+in the t/op/numconvert test because of this.  (The data is still good
+internally, and the "%e" format of printf() or sprintf() in perl will still
+produce valid results.)  See README.tru64 for additional details.
+
+Continuing anyway.
