FYI, _Static_assert is not a FreeBSD-ism, it's part of C11. Our old CTASSERT is a FreeBSD-ism that this extends, but really, these should be implemented in terms of _Static_assert when possible. Something like: #if is_c11 #define __CTASSERT(x) __Static_assert(x) #else /* all the rest */ #endif If __CTASSERT0 is used directly anywhere, you could emulate it via something like #define __CTASSERT0(x, y, z) __Static_assert(x, __STRING(y) "_" __STRING(z)) (Note that we build all of userspace as C17 by default in 15.0 and later.) -- John Baldwinhome | help
