OK - read everything I can and spent months on this..

I need to be able to write code which will parse :

        define date date

or even

        define define date

(and a lot more besides...)


which defines a variable called 'date' or 'define' to be a date datatype...
(I didn't write the language)

We've got something that tries to work out whether the next token should be an 
identifier or not and runs accordingly, by looking at the y.output and 
generating a list of possible next tokens..

This works for 80% of the cases - but we get into problems when we move around 
the bison stack...

SO - 

Is there a version of Bison which can handle this situation ?

Are there any simple solutions (maybe using other compatible compilers - I've 
got a lot of code so I don't want to manually convert it) ?

Are there any hacks I can make in Bison  ?

I was thinking about trying YYERROR (if it doesn't process - treat it as an 
identifier and try again) - How would I go about this ?


Any help much appreciated..
