Hallo netlanders,

I've a great problem porting a yacc-grammar to bison.
one point is the variable yynerrs, used by yacc and not supported
from bison. 
Where do i have to declare and increment it ?

The next point is error-handling. I introduced error-symbols
in the grammar following kernighan & pike's rules. everything goes
ok using yacc. But bison produces errors even in an error-free
grammar, and can't recover from the first error produced by
the first token of the inputfile.

Did anybody have such problems ???

	any comments gracefully accepted
