does the _t reservation also include local variable names?

this should be forwarded to xvid-dev so they can fix it when they break
compatiility nex time

will fix though this is not my fault it seems:

 4040     lorenm } dwt_compose_t;
 9069     lorenm } heap_elem_t;

i dont maintain *_bfin, i dont even know _bfin asm nor could i test bfin
due to not having a bfin
