It is still not acceptable to standard C.  In addition, if you
examine the generated code, you may find that is has been converted
to my code in the first place, or that it is generating a 2000
entry transfer table (may depend on optimization), which is not
exactly optimum code.  It doesn't hurt to have a rough idea of what
the compiler generates.
