To avoid overriding calc.c if it's a separate source file.

I.e., the output goes to the current directory!

But automake doesn't need all those files - it only needs the parcer.

I realize that.

It's unfortunate that the native mode of Bison behaves in a less uniform
way than the yacc mode. I agree with your point. Bison maintainters may
want to fix it along with the documentation.
