>Description:
NetBSD has declarations of __CTASSERT() in <sys/cdefs.h>. We only have it in
<sys/systm.h> which is a kernel space header. Since we are mirroring code from
NetBSD that might use __CTASSERT() in user space, e.g., vis(3), we need to add
or move __CTASSERT().
>How-To-Repeat:
n/a
>Fix:
The NetBSD code in <sys/cdefs.h> is:
/*
* Compile Time Assertion.
*/
#ifdef __COUNTER__
#define __CTASSERT(x) __CTASSERT0(x, __ctassert, __COUNTER__)
#else
#define __CTASSERT(x) __CTASSERT0(x, __ctassert, __LINE__)
#endif
#define __CTASSERT0(x, y, z) __CTASSERT1(x, y, z)
#define __CTASSERT1(x, y, z) typedef char y ## z[(x) ? 1 : -1];
