     The C compiler for the Intergraph Clipper is able to know the lifetime
of a variable and can reuse the same register.  They call this 'register
allocation by coloring'.  This is done in addition to many other optimizations,
and the variables do not need to be declared register in order for the complier
to do this.  Of course this is not of much help to use Amiga owners.
