From 390b5a4727924503095327087c5d5f7a369732ef Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Wed, 12 Feb 2020 10:42:49 +0100 Subject: [PATCH] y2038: include: Move struct __timespec64 definition to a separate file The struct __timespec64's definition has been moved from ./include/time.h to ./include/struct___timespec64.h. This change would prevent from polluting other glibc namespaces (when headers are modified to support 64 bit time on architectures with __WORDSIZE==32). Now it is possible to just include definition of this particular structure when needed.
