- * A state transition function alters the global #if processing state
- * in a particular way. The table below is indexed by the current
- * processing state and the type of the current line.
- *
- * Nesting is handled by keeping a stack of states; some transition
- * functions increase or decrease the depth. They also maintain the
- * ignore state on a stack. In some complicated cases they have to
- * alter the preprocessor directive, as follows.
- *
- * When we have processed a group that starts off with a known-false
- * #if/#elif sequence (which has therefore been deleted) followed by a
- * #elif that we don't understand and therefore must keep, we edit the
- * latter into a #if to keep the nesting correct.
- *
- * When we find a true #elif in a group, the following block will
- * always be kept and the rest of the sequence after the next #elif or
- * #else will be discarded. We edit the #elif into a #else and the
- * following directive to #endif since this has the desired behaviour.
- *
- * "Dodgy" directives are split across multiple lines, the most common
- * example being a multi-line comment hanging off the right of the
- * directive. We can handle them correctly only if there is no change
- * from printing to dropping (or vice versa) caused by that directive.
- * If the directive is the first of a group we have a choice between
- * failing with an error, or passing it through unchanged instead of
- * evaluating it. The latter is not the default to avoid questions from
- * users about unifdef unexpectedly leaving behind preprocessor directives.
