It comes up occasionally. It would be better to create one.

Maybe something like
/*
* Description goes here
*/
#define BUILD_BUG_ON_STATIC(unique_id, expr) \
typedef char unique_id[1-2*(expr)];
BUILD_BUG_ON_STATIC(__check_printf_spec, sizeof(struct printf_spec) != 8);
("static" seems the wrong term, but what is the correct term for
"outside of functions"?)
(I hope this patchset is still up-to-date)
