1. To get yacc's default output names (y.output, y.tab.c and y.tab.h) instead
of Bison's output names, you need to use the -y switch.
2. Bison's generated parser uses the Vax alloca() function, which you may
3. Despite claims in the code, Bison's generated parser was for me
slightly slower than yacc's, not that this is a genuine concern.
4. Bison itself runs about 7 times as fast as yacc. This is
insignificant on normal grammars, but, on the large (Cobol-85) grammar
I am using, it goes from 15 minutes to 2-1/2 - an obvious boon.
5. Bison's generated parser has a copyright notice in it which prevents
you from embeddding the result in a proprietary product.
6. Apart from the above issues, Bison plugs straight in.
