We had the same problem. It can be solved by modifying file nios2-linux/gcc3/gcc/c-parse.y. From the line 1650, 1661, 1670 and 1675 modify $$ to $<ttype>$. For example change the line 1650 from { $$ = start_struct (RECORD_TYPE, $2); to { $<ttype>$ = start_struct (RECORD_TYPE, $2);

 I can't imagine how you figured that out.
