libstdc++-v3/ChangeLog: * include/bits/semaphore_base.h: Include <exception> and <errno.h>. Tested x86_64-linux. Committed to trunk. This should be backported to gcc-11 but it can wait until after the 11.1 release. It affects non-linux targets which have POSIX semaphores. For linux targets the <cerrno> header gets included in <bits/atomic_wait.h> but for non-linux it doesn't. The testsuite is not picking this up, probably because the testsuite is cursed by PCH by default. commit a38b1a59f8eb6f41a885f8a7c8838378be717b02 Author: Jonathan Wakely <jwakely@redhat.com> Date: Mon Apr 26 12:28:37 2021 libstdc++: Add missing headers for errno and std::terminate libstdc++-v3/ChangeLog: * include/bits/semaphore_base.h: Include <exception> and <errno.h>.
