Subject: RE: [PATCH next 02/11] minmax: Use _Static_assert() instead of static_assert()
Date: Sun, 28 Jan 2024 19:27:01 +0000 [thread overview]
Message-ID: <bfdbd45e23c840988540dc0d810f8e21@AcuMS.aculab.com> (raw)
In-Reply-To: <0ca26166dd2a4ff5a674b84704ff1517@AcuMS.aculab.com>
The wrapper just adds two more lines of error output when the test fails.
