Some obscure C features you might not know about

I have been working on Snow, a unit testing library for C. I wanted to see how close I could come to making a DSL (domain specific language) with its own syntax and features, using only the C preprocessor and more obscure C features and GNU extensions. I will not go into detail about how Snow works unless it's directly relevant, so I recommend taking a quick look at the readme on the GitHub page...
