The occurences of "int" and "float" in the grammar have the side-effect of
registering these strings as keywords for the grammar lexer, but the Caml
grammar expect these to be regular identifiers, not keywords. Note that
you also register other keywords that could be used by OCaml code (e.g.
Type).
One possible solution is to use
LIDENT "int"
instead of
"int"
in your grammars (I didn't try it on your example, though).
Cheers,
Alain
