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.
