True, but GNAT's preprocessor symbols should keep things
reasonably sane? Unless the programmer chooses to define
substitutes for words like "package", say, in which case
the preprocesor will have to know the substitute. Not for
actually replacing, but for deciding where gnatchop should
should chop.
