pure bison and YYPARSE_PARAM

Hi all,

Using flex and bison in a pure context.

Flex generates yylex/2 lval as first arg and lloc as second

Specifying pure-parser in *.y file yields proper yylex calling.

However the flex example calles bison as

        yyparse( Lexer )

Where lexer is the datastructure allocated by yylex_init containing the state 
of the lex parser.

However yyparse generally has NO arguments EXCEPT if YYPARSE_PARAM e.a. is 
used.

However the info for bison states that his define is depreciated ... 

What is then the alternative to pass the lexer to the bison parser ?

Thanx

W
