/*
 * Provide a version of static_assert() that is guaranteed to have an optional
 * message param.  _GNU_SOURCE is defined for all KVM selftests, _GNU_SOURCE
 * implies _ISOC11_SOURCE, and if _ISOC11_SOURCE is defined, glibc #undefs and
 * #defines static_assert() as a direct alias to _Static_assert() (see
 * usr/include/assert.h).  Define a custom macro instead of redefining
 * static_assert() to avoid creating non-deterministic behavior that is
 * dependent on include order.
