I'll look into it at some point if I find the time.

If memory serves I removed the byte stack not only for performance reasons, but 
also because the byte stack implementation relies on using pointers to freed 
storage, which violates the C standard. Although we've been lucky that this 
works on Emacs platforms so far, our luck will run out once we get Emacs to work 
with gcc -fcheck-pointer-bounds.
