From b997083e3d30dc165d8e6dd3b6a126259824033e Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Thu, 22 Oct 2020 12:04:40 +0200 Subject: y2038: Use a common definition for msqid_ds Instead of replicate the same definitions from struct_msqid64_ds.h on the multiple struct_msqid_ds.h, use a common header which is included when required (struct_msqid64_ds_helper.h). The __USE_TIME_BITS64 is not defined internally yet, although the internal header is used when building the 64-bit stat implementations.
