+Subject: [PATCH 1/2] fix: allow 64-bit time_t on 32-bit systems in
+ test_is32bit
+
+Some modern 32-bit Linux systems (e.g. with glibc >= 2.34 or musl time64 ABI)
+use 64-bit time_t by default when _TIME_BITS=64 is enabled. The original test
+assumed time_t was always 32-bit on 32-bit architectures, which is no longer
+true.
+
+Relax the check to accept both 32-bit and 64-bit time_t values:
+
+ self.assertIn(bit32, (32, 64))
+
+This makes the test compatible with both legacy and time64 ABIs.

+Subject: [PATCH 2/2] fix: correct struct packing on 32-bit with _TIME_BITS=64
+
+On 32-bit platforms with glibc time64 ABI, time_t is 64-bit wide while
+`long` remains 32-bit. This causes struct timeval to use two 64-bit fields
+(tv_sec, tv_usec). The previous code incorrectly packed timeout as "ll",
+leading to EINVAL in setsockopt(SO_RCVTIMEO).
+
+Use "qq" instead when m2.time_t_bits() == 64 to match the actual ABI.
