Subject: Re: [PATCH v3] Always define __USE_TIME_BITS64 when 64 bit time_t is used
Date: Sat, 27 Jan 2024 14:54:35 +0100 [thread overview]
Message-ID: <2445957.jE0xQCEvom@pinacolada> (raw)
In-Reply-To: <20240118131801.600373-1-adhemerval.zanella@linaro.org>
When rebuilding a riscv32 qemu chroot with this patch I get errors similar to
(python)

Now, this chroot is *very* experimental, may have stale files lying around
from bootstrapping, and has significant other problems.
And I havent tried updating it for a while. But this looks related?
