Thanks...it has definitely been a long road.  The LL(*) parsing  
strategy and the other goodies + Jean's ANTLRWorks should definitely  
make ANTLR the clear choice for most practical recognition/ 
translation tasks. :)

Has anybody checked out the LL-star example in the examples-v3  
tarball?  It's totally non-LL(k) for any fixed k but ANTLR v3 munches  
it and generates a nice little parser for it.  At least on my box,  
ANTLRWorks does a nice job to highlighting the variable-length  
lookahead in blue as it moves through the simple C input.  :)  The LL 
(*) decision is this one:

decl  :    functionHeader ';' // declaration
          |    functionHeader body // definition
         |    variable
         ;

or something like that.  Anyway, note the arbitrarily long left- 
common prefix on the first two alts. :)
