how does one pass args to yyparse and yylex?

[Dean NEWTON]

Two questions regarding yacc and lex:

1) How does one pass args to yyparse and yylex from a C program?

2) How can one declare local variables in yyparse and yylex?

I have managed to do both of these by using a sed script in my makefile,
but it's ugly.  There has to be a better way.

Thanks,
