Breaking changes ?

[Mike Aubury]

Hi,

I've just tried compiling our opensource software using bison 3.0.2 - and
it seems %pure_parser isn't doing "what it used to do".

I'm getting a "depreciated" message and told to change to "%pure-parser" -
which i've done but can you point me to any docs on how to get it so yylex
is called with the same parameters as before:

yylex (void *pyylval, int yystate, void *yys1, void *yys2);


In particular - I *need* yystate..


Also - are these changes compatible so the same file will compile with
older versions of bison ?


Thanks in advance
