Hi!

     In my previous example of portability macros (which was written from
memory) I miss another optimization trick. Was:

#define hibyte(v) lobyte ((v) >> 8)

Should be (as in my patch):

#define hibyte(v) lobyte ((UWORD)(v) >> 8)
>-------------------------^^^^^^^

So, now you may apply "hibyte (Cluster2)" and don't worry if Cluster2 is
long or short value: it will be automatically optimized short access (or,
in worser case, as with BC, into shorter shift, which applied by CPU
instruction, not by call to internal routine).
