/* FSF LOCAL dje prefix attributes */
/* Split SPECS_ATTRS, a list of declspecs and prefix attributes, into two
lists. SPECS_ATTRS may also be just a typespec (eg: RECORD_TYPE).
The head of the declspec list is stored in DECLSPECS.
The head of the attribute list is stored in PREFIX_ATTRIBUTES.
Note that attributes in SPECS_ATTRS are stored in the TREE_PURPOSE of
the list elements. We drop the containing TREE_LIST nodes and link the
resulting attributes together the way decl_attributes expects them. */

This function is used by the parser when a rule will accept attributes
in a particular position, but we don't want to support that just yet.
