From 93277314f0ec84409e15f6e2cd616d028cb53065 Mon Sep 17 00:00:00 2001 From: Ed Wildgoose Date: Tue, 16 Jun 2020 15:00:56 +0100 Subject: Rename __unused struct members to include a namespace Rename various spare fields in structs to include a namespace This should avoid accidental clashes with uses of the __unused symbol in upstream projects. eg currently it causes a compile error in dhcpcd 8.x due to their re-use of the __unused symbol as a macro This follows the style of glibc which does something equivalent --- libc/sysdeps/linux/x86_64/bits/fenv.h | 10 +++++----- libc/sysdeps/linux/x86_64/bits/kernel_stat.h | 2 +- libc/sysdeps/linux/x86_64/bits/msq.h | 10 +++++----- libc/sysdeps/linux/x86_64/bits/sem.h | 8 ++++---- libc/sysdeps/linux/x86_64/bits/shm.h | 18 +++++++++--------- libc/sysdeps/linux/x86_64/bits/stat.h | 8 ++++---- 6 files changed, 28 insertions(+), 28 deletions(-) (limited to 'libc/sysdeps/linux/x86_64/bits') diff --git a/libc/sysdeps/linux/x86_64/bits/fenv.h b/libc/sysdeps/linux/x86_64/bits/fenv.h index 8e38c16ec..f16b64ad3 100644 --- a/libc/sysdeps/linux/x86_64/bits/fenv.h +++ b/libc/sysdeps/linux/x86_64/bits/fenv.h @@ -69,18 +69,18 @@ typedef unsigned short int fexcept_t;
