+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.
