I don't think so, but if you need to do that sort of thing you can 
usually just factor it out into a subrule.  (If you can't factor 
it out into a subrule, then your variable may not be as local as 
you thought, and you might as well just declare it at the 
top.  This is C, after all -- while it permits declarations at the 
start of any block it's most common to only declare variables at 
the function entrypoint.
