Well, they map very directly to stack operations, some of which
are also Forth words.  But, that subset of Forth is not Forth
either...  Stack operations are a Forth subset.  I.e., if you were
converting C to equivalent Forth - not just stack operations which
may have Forth definitions - it'd be a larger task.  In that case,
you couldn't just emit Forth stack operations.  You'd need to emit
higher level Forth words too, like ALLOC or CONSTANT or
PARSE etc.  In theory, it's possible to build these back up to
higher level Forth words from the stack operations.  However, it's
generally more convenient to convert directly to high level Forth.
