Hmm. I suspect that I could shrink our gram.y by ~25% just by removing
comments and C support routines, and by consolidating some execution
blocks onto fewer lines. Does it look like their parse.y is more dense
than ours, do they do a lot of postprocessing to eliminate the yacc
rules, or have we missed the boat on writing the grammar in yacc?

Just curious; I probably won't look myself since I don't want to run the
risk of compromising our code and licensing. Or is that not an issue
with the Inprise license?
