* foomatic foo; // gap=2
* SS_INCLUDE:

* char *bar; // gap=6, as the '*' doesn't count
* foomatic foo; // gap=2
* Right aligned numbers:
* #define A -1
* #define B 631
* #define C 3
* Left aligned numbers:
* #define A -1
* #define B 631
* #define C 3
*
* In the code below, pc is set to the item that is aligned.
* In the above examples, that is 'foo', '*', '-', or 63.
*
* Ref is set to the last part of the type.
* In the above examples, that is 'void', 'char', 'foomatic', 'A', or 'B'.
*
* The '*' and '&' can float between the two.
