How about changing the grammar to define something like:

attributes:
     td_attribs
   | tCONTEXTHANDLE
   | tSTRING
   | ... /* other things that can't be a typedef */
    ;

td_attribs:
     tAGGREGATABLE
   | ... /* other things in the existing attributes rule */
   ;

typedef: tTYPEDEF td_attribs type pident_list
     ....

That way the parser can deal with the problem.
