Note that unless you have the case (a) you will have to configure
and compile Perl using the -Duse64bits Configure flag.
-Unfortunately bit arithmetics (&, |, ^, ~, <<, >>) are not 64-bit clean.
+Unfortunately bit arithmetics (&, |, ^, ~, <<, >>) are not 64-bit clean,
+they are explictly forced to be 32-bit.
Last but not least: note that due to Perl's habit of always using
floating point numbers the quads are still not true integers.
