Cool, this seems useful. Have you considered an implementation
strategy more along the lines of egypt (in ports/devel/egypt)?
Egypt has two important advantages. First, it lets gcc interpret
the source code instead of using an ad hoc C lexer. Second, it
generates output for dot (ports/graphics/graphviz), which is
arguably the most popular free tool for generating graph diagrams
in Unix. At least the first of these properties is highly desirable
because it means that the tool can interpret any program that cc(1)
can interpret, instead of some highly constrained subset of them.
