[Haskell-cafe] Generate Fortran 77 parser from a yacc grammar using Happy

[Cetin Sert]

I have stumbled upon the following F77 yacc grammar:
http://yaxx.cvs.sourceforge.net/viewvc/yaxx/yaxx/fortran/fortran.y?revision=1.3view=markup
.

How can I make a Fortran 77 parser out of this file using
Happyhttp://www.haskell.org/happy/
?

Why is there some C?/C++? code in that .y file?

It has the look of a production grammar with the reduction actions  
stripped out (but whatever they used didn't strip the %{ initializer  
block).  I would say that, for starters, you want to strip or modify  
the %{ block, and possibly remove/replace the empty { } actions in the  
grammar.  More I can't say; I know yacc, not happy.
