From f0065f207cf19cd960b33d961472c6d69514336f Mon Sep 17 00:00:00 2001 From: Samuel Thibault Date: Fri, 7 Oct 2022 22:45:06 +0200 Subject: [PATCH] libstdc++: Mark pieces of gnu-linux/os_support.h linux-specific This is notably needed because in glibc 2.34, the move of pthread functions into libc.so happened for Linux only, not GNU/Hurd. The pthread_self() function can also always be used fine as it is on GNU/Hurd. libstdc++-v3/ChangeLog: * config/os/gnu-linux/os_defines.h [!__linux__] (_GLIBCXX_NATIVE_THREAD_ID, _GLIBCXX_GTHREAD_USE_WEAK): Do not define.
