Parsing C is orders of magnitude simpler than Perl. Not even perl can always pass Perl.

But even if you have such a regex, to actually find out whether a variable is unused or not, you've got to know what a piece of code will do. To determine that at compile time, you need to solve the halting problem.

If you solve the halting problem, I'll do the regex.
