The other day I ran into an interesting problem: how can you write a C preprocessor macro that removes parentheses surrounding its argument, but leaves the argument alone if no parentheses are present? For today's article, I'm going to share my solution.

It's been a bit since I did an article, but I'm back again, with a somewhat off-the-cuff treatment of a very twisted set of code I use to pretend that C has exceptions. I delve into little-known extensions of C, Linux compatibility, and worst of all, goto, so be warned!
