100       val warning_attribute : ?ppwarning:bool -> Parsetree.attribute -> unit
101
102       Apply warning settings  from  the  specified  attribute.   "ocaml.warn‐
103       ing"/"ocaml.warnerror"  (and variants without the prefix) are processed
104       and other attributes are ignored.
105
106       Also implement ocaml.ppwarning (unless ~ppwarning:false is passed).

109
110       val warning_scope : ?ppwarning:bool -> Parsetree.attributes -> (unit ->
111       'a) -> 'a
112
113       Execute  a  function  in  a new scope for warning settings.  This means
114       that the effect of any call to warning_attribute during  the  execution
115       of this function will be discarded after execution.
116
117       The  function  also takes a list of attributes which are processed with
118       warning_attribute in the fresh scope before the function is executed.
