- That structure contains arithmetic operations in reverse polish,

- See expression.h for the details of the format.
- What is important here is that it can be built up sequentially
- during the process of parsing; the lower levels of the tree always

-
- Note that malloc's and realloc's in this file are transformed to
- xmalloc and xrealloc respectively by the same sed command in the
- makefile that remaps any other malloc/realloc inserted by the parser
- generator. Doing this with #defines and trying to control the interaction
- with include files (<malloc.h> and <stdlib.h> for example) just became
- too messy, particularly when such includes can be inserted at random
