Some other implementations of Ruby are different. With [[JRuby]], a Fixnum is always 64 bits, because it is a Java <code>long</code> [http://www.jruby.org/git?p=jruby.git;a=blob;f=src/org/jruby/RubyFixnum.java;h=ba8d076d58d28c30ecd8e378e6e2482486dba22d;hb=HEAD#l91 (1)]. JRuby uses the correct native byte order by calling java.nio.ByteOrder.nativeOrder() [http://www.jruby.org/git?p=jruby.git;a=blob;f=src/org/jruby/platform/Platform.java;h=d84b0b55b1aca381b2101297185d3b7f872c8cfd;hb=HEAD#l110 (2)].
