Tru64 V5.0, the long double support simply wasn't functional before
that.
+At the time of this writing, there's a bug in the Tru64 libc printing
+of long doubles when not using "e" notation. The values are correct
+and usable, but you only get a limited number of digits displayed
+unless you force the issue by using C<printf "%.33e",$num> or the like.
+For Tru64 versions V5.0A through V5.1A, a patch is expected sometime after
+perl 5.8.0 is released. If your libc has not yet been patched, you'll get
+a warning from Configure when selecting long doubles.

=head2 64-bit Perl on Tru64
In Tru64 Perl's integers are automatically 64-bit wide, there is
cannot be tested before Perl has been installed. The test refers to
the use of the C<-P> option of Perl.
+=head1 ext/ODBM_File/odbm Test Failing With Static Builds
+
+The ext/ODBM_File/odbm is known to fail with static builds
+(Configure -Dusedl) due to a known bug in Tru64's static libdbm
+library. The good news is that you very probably don't need to ever
+use the ODBM_File extension since more advanced NDBM_File works fine,
+not to mention the even more advanced DB_File.
