Based on the code shown in this article, I'm not clear on how you would actually do that. It *looks* like the macro expands to while(something) or for(something), and doesn't even have the "regular" set of braces, so you can't edit it to include an outer set of braces without modifying the call sites.

I don't think you could with Linux's list macros. You could with Sparse's, which have pairs of macros invoked at the start and end of each loop (and which use two levels of braces).

But C99 makes this easy.
