+
+In 5.005_0x and earlier, perl's rand() function used the C library
+rand(3) function.  As of 5.005_52, Configure tests for drand48(),
+random(), and rand() (in that order) and picks the first one it finds.
+Perl programs that depend on reproducing a specific set of pseudo-random
+numbers will now likely produce different output.
