/* This was blantantly ripped off the C expression parser, please
be aware of that as you look at its basic structure -FMB */
/* Parse a F77 expression from text in a string,
and return the result as a struct expression pointer.
That structure contains arithmetic operations in reverse polish,
with constants represented by operations that are followed by special data.
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
come first in the result.
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
times by the parser generator. */
